Starting from rest, a 5.00-kg block slides 2.50 m down a rough $30.0 ^ { \circ }$ incline. The coefficient of kinetic friction between the block and the incline is $\mu _ { k } = 0.436$. Determine the work done by the friction force between block and incline.

You put some ice cubes in a glass, fill the glass with cold water, and then let the glass sit on a table. Describe how the temperature of the water changes as time passes. Then sketch a rough graph of the temperature of the water as a function of the elapsed time.

A popular amusement park ride whisks riders to the top of a $250$-foot tower and drops them at speeds exceeding $50$ miles per hour. A function for the path of a rider is $h=-16 t^2+ 250$ , where $h$ is the height and $t$ is the time in seconds.

The ride stops the descent of the rider $40$ feet above the ground. Write an equation that models the drop of the rider.

A $51-\mathrm{kg}$ packing crate is pulled with constant speed across a rough floor with a rope that is at an angle of $43.5^{\circ}$ above the horizontal. If the tension in the rope is $115 \mathrm{~N}$, how much work is done on the crate to move it $8.0 \mathrm{~m}$ ?

Draw a rough sketch of the graphs of each of the given pairs of functions. Use your sketch to approximate the point(s) of the intersection of the two graphs, and then apply Newton's method to refine the approximation of the $x$-coordinate of the point of intersection. $f(x)=e^{-x^2} ; g(x)=x^2$

A stuntman is being pulled along a rough road at a constant velocity by a cable attached to a moving truck. The cable is parallel to the ground. The mass of the stuntman is 109 kg, and the coefficient of kinetic friction between the road and him is 0.870. Find the tension in the cable.

Graph x and y as functions of t and observe how x and y increase or decrease as t increases. Use these observations to make a rough sketch by hand of the parametric curve. Then use a graphing device to check your sketch. \

$$x=\cos t, \quad y=\tan ^{-1} t$$

We met the Tour de France data set in Chapter 1 (in Just Checking). One hundred years ago, the fastest rider finished the course at an average speed of about $25.3 \mathrm{kph}$ (around $15.8 \mathrm{mph}$ ). By the $21 \mathrm{st}$ century, winning riders were averaging over $40 \mathrm{kph}$ (nearly $25 \mathrm{mph}$ ).

a) Make a scatterplot of Avg Speed against Year. Describe the relationship of Avg Speed by Year, being careful to point out any unusual features in the plot.

b) Find the regression equation of Avg Speed on Year.

c) Are the conditions for regression met? Comment.

The uniform box of mass m slides down the rough incline. Determine the location d of the effective normal force N. The effective normal force is located at the centroid of the nonuniform pressure distribution which the incline($\mu_{k}$) exerts on the bottom surface of the block.
