A car is towing a boat on a trailer. The driver starts from rest and accelerates to a velocity of + 11 m/s in a time of 28 s. The combined mass of the boat and trailer is 410 kg. The frictional force acting on the trailer can be ignored. What is the tension in the hitch that connects the trailer to the car?

To make $60 \mathrm{lb}$ pounds of a trail mix selling for $\$ 5$ per $\mathrm{lb}$ pound, how many pounds of nuts selling for $\$ 6$ per $\mathrm{lb}$ pound and raisins selling for $\$ 3$ per $1 \mathrm{~b}$ pound should Theresa combine?

Zoey made 5$\frac{1}{2}$ cups of tual mix for a camping trip. She wants to divide the trail mix into $\frac{3}{4}$ -cup servings. a. Ten people are going on the camping trip. Can Zoey make enough $\frac{3}{4}$ -cup servings so that each person on the trip has one serving?
b. What size would the servings need to be for everyone to have a serving? Explain. c. If zoey decides to use the $\frac{3}{4}$ -cup servings, how much more trail mix will she need? Explain.

In the following sentence, identify the underlined pronouns by writing above each one PER for personal, REF for reflexive, INTEN for intensive, DEM for demonstrative, INTER for interrogative, REL for relative, or IND for indefinite.

The cyclists took $\underline{\text{their}}$water bottles with $\underline{\text{them}}$on the trail.

Use the data to complete the line plot. Then answer the questions. A clerk in a health food store makes bags of trail mix. The amount of trail mix in each bag is listed below.

$$\frac{1}{4}lb,\frac{1}{4}lb,\frac{3}{4}lb,\frac{1}{2}lb,\frac{1}{4}lb,\frac{3}{4}lb,\frac{3}{4}lb,\frac{3}{4}lb,\frac{1}{2}lb,\frac{1}{4}lb,\frac{1}{2}lb,\frac{1}{2}lb$$

What is the combined weight of the

$$\dfrac{1}{2}lb$$

bags?

These words in the poem help convey the passions and exploits of war. Substitute the boldfaced word in each of the following sentences with a word from the list. Word list: abstain, defile, felicity, havoc, ponderous, rancor, scourge, vulnerable. The monster left behind a terrible trail of $\textbf{devastation.}$

A car pulls a trailer down the highway. Let $F_1$ be the magnitude of the force on the trailer due to the car, and let $F_c$ be the magnitude of the force on car due to the trailer. If the car and trailer are moving at a constant velocity across level ground, then $F_{\mathrm{l}}=F_{\mathrm{c}}$. If the car and trailer are accelerating up a hill, what is the relationship between the two forces?

Greg is on a 32-mile bicycle trail from Elroy, Wisconsin, to Sparta, Wisconsin. He leaves Elroy at 9:30 A.M. and arrives in Sparta at 2:00 P.M. Graph the line that represents Greg’s distance from Elroy at a given time. Find and interpret the slope of the line.

A $66 \mathrm{~kg}$ skier starts from rest at the top of a $1200 \mathrm{~m}$ long trail which drops a total of $230 \mathrm{~m}$ from top to bottom. At the bottom, the skier is moving $11.0 \mathrm{~m} / \mathrm{s}$. How much energy was dissipated by friction?

Suppose you park your car at a trailhead in a national park and begin a 2-hr hike to a lake at 7 A.M. on a Friday morning. On Sunday morning, you leave the lake at 7 A.M. and start the 2-hr hike back to your car. Assume the lake is 3 mi from your car. Let f(t) be your distance from the car t hours after 7 A.M. on Friday morning and let g(t) be your distance from the car t hours after 7 A.M. on Sunday morning. Use the Intermediate Value Theorem to show that there is some point along the trail that you will pass at exactly the same time of morning on both days.

Greg is on a 32-mile bicycle trail from Elroy, Wisconsin, to Sparta, Wisconsin. He leaves Elroy at 9:30 A.M. and arrives in Sparta at 2:00 P.M. Graph the line that represents Greg's distance from Elroy at a given time. Find the interpret the slope of the line.

A car pulls a trailer down the highway. Let $F_{\mathrm{t}}$ be the magnitude of the force on the trailer due to the car, and let $F_{\mathrm{c}}$ be the magnitude of the force on the car due to the trailer. If the car and trailer are moving at a constant velocity across level ground, then $F_{\mathrm{t}}=F_{\mathrm{c}}$. If the car and trailer are accelerating up a hill, what is the relationship between the two forces?

In what ways might Illinois, Wisconsin, and Oregon all be considered trailblazers in progressive reform? Support your answers.

A $1200 \mathrm{~kg}$ trailer is hitched to a $1400 \mathrm{~kg}$ car. The car and trailer are traveling at $72 \mathrm{~km} / \mathrm{h}$ when the driver applies the brakes on both the car and the trailer. Knowing that the braking forces exerted on the car and the trailer are $5000 \mathrm{~N}$ and $4000 \mathrm{~N}$, respectively, determine $(a)$ the distance traveled by the car and trailer before they come to a stop, $(b)$ the horizontal component of the force exerted by the trailer hitch on the car.
