a. What types of graphs can you use to analyze the acceleration of an object? b. How is an object moving if a slanted, straight line on a speed-versus-time graph represents its motion? c. What would a distance-versustime graph look like for the moving object in part (b)?

a. Identifying What formula do you use to calculate the acceleration of an object moving in a straight line? b. Calculating The velocity of a cyclist moving in a straight line changes from 0 m/s to 15 m/s in 10 seconds. What is the cyclist's acceleration?

a. What is the formula used to calculate the acceleration of an object moving in a straight line? b. A cyclist's speed changes from $0 \mathrm{~m} / \mathrm{s}$ to $15 \mathrm{~m} / \mathrm{s}$ in 10 seconds. What is the cyclist's average acceleration?

a. What is the formula used to calculate the acceleration of an object moving in a straight line? b. A cyclist's speed changes from 0 m/s to 15 m/s in 10 seconds. What is the cyclist's average acceleration?

If you know a car travels $30 \mathrm{~km}$ in 20 minutes, you can find its a. acceleration. b. average speed. c. direction. d. instantaneous speed.

The speed you calculated in Question 21 is also the speed the ladybug had at the end of its acceleration at line B. If it took 2 seconds for the ladybug to accelerate from the start line to line $\mathrm{B}$, what is its average acceleration during that time?

Starting at rest, the ladybug accelerated to line $\mathrm{B}$ and then moved at a constant speed until it reached the finish line. If the ladybug took $2.5$ seconds to move from line B to the finish line, calculate its constant speed during that time.

Measure the distance from the starting line to line $\mathrm{B}$, and from line $\mathrm{B}$ to the finish line. Measure to the nearest tenth of a centimeter.

During a slap shot, a hockey puck takes $0.5$ second to reach the goal. It started from rest and reached a final speed of $35 \mathrm{~m} / \mathrm{s}$. What is the puck's average acceleration?

Convert 22.4 km to meters

You do not know an object's velocity until you know its a. speed and distance. b. reference point. c. speed and direction. d. acceleration.

a. What is the SI unit for length? b. How many centimeters are there in a meter? How many meters are there in a kilometer? c. This week at swim practice, Jamie swam a total of $1,500 \mathrm{~m}$, while Ellie swam $1.6 \mathrm{~km}$. Convert Ellie's distance to meters. Which swimmer swam the greater distance?

a. What does the slope of a distanceversus-time graph show you about the motion of an object? b. The rise of a line on a distanceversus-time graph is $600 \mathrm{~m}$ and the run is 3 minutes. What is the slope of the line?

Your father is driving to the beach. He drives at one speed for two hours. He drives at a different speed for another two hours and a third speed for the final hour. How would you find his average speed for all five hours? F Divide the total driving time by the total distance. G Multiply the total driving time by the total distance. H Divide the total distance by the total driving time. J Subtract the total driving time from the total distance.
