Unit 2 Test Review: Motion in 1 Dimension

  1. A mouse runs a distance of 2m in 15 seconds. What is his speed?
  1. Jose travelled at a speed of 18km/h for 2 hours. What distance did he cover?
  1. A train travels at a speed of 30 mph and traveled a distance of 240 miles. How long did it take the train to complete its journey?
  2. A helicopter’s speed increases from 25m/s to 60 m/s in 5 seconds. What is the acceleration of this helicopter?
  3. From rest a race car can accelerate to 100km/h over a distance of 50m. What is the race car’s acceleration?
  4. If a car travels 400m in 20 seconds how fast is it going?
  1. A roller coaster car rapidly picks up speed as it rolls down a slope. As it starts down the slope, its speed is 4 m/s. But 3 seconds later, at the bottom of the slope, its speed is 22 m/s. What is the coaster car’s average acceleration?
  1. How much time will it take for a bug to travel 55 meters across the floor if it is traveling at 5 m/s?
  1. A lizard accelerates from 2 m/s to 10 m/s in 4 seconds. What is the lizard’s average acceleration?
  1. If you shout into the Grand Canyon, your voice travels at the speed of sound (340 m/s) to the bottom of the canyon and back, and you hear an echo. How deep is the Grand Canyon at a spot where you can hear your echo 5.2 seconds after you shout?
  2. You are standing beside the road watching two vehicles--a dump truck and a tow truck--passing by. The tow truck travels 15 m/s to the left, and the dump truck 10 m/s to the right. What is the tow truck’s motion relative to the dump truck?
  3. An ant travels 10cm to the right on a plate relative to the plate as a disgusted picnicker pushes the plate a distance of 40 cm to the right relative to the earth. What is the displacement of the ant with respect to the earth?
  4. A Cadillac is traveling northward at 100 km/hrrelative to the earth. A motorcycle is traveling northward at 80 km/hr relative to the earth. Determine
    (a) the velocity of the Cadillac with respect to the motorcycle;

(b) the velocity of the motorcycle with respect to the Cadillac.

A cart moves along a straight track. Its initial movement is toward the south. Below is the position-time graph of the cart. Use the information in the graph to answer the questions.

Check all that apply.

1. In which interval(s) was the cart at rest? □AB □BC □CD □DE □EF □FG □GH

2. In which interval(s) was the cart traveling to the north?

□AB □BC □CD □DE □EF □FG □GH

3. In which interval(s) was the cart traveling to the south?

□AB □BC □CD □DE □EF □FG □GH

4. In which interval did the cart maintain the greatest average speed?

□AB □BC □CD □DE □EF □FG □GH

6. What was the cart’s total displacement during these 11 seconds?

7. What was its averagevelocity during these 11 seconds?

8. What was the cart’s total distance traveled during these 11 seconds?

9. What was its average speed during these 11 seconds?

  1. A cart travels with a constant nonzero acceleration along a straight line. Which graph best represents the relationship between the distance the cart travels and time of travel?
  1. Which graph best represents the motion of a block accelerating uniformly down an inclined plane?
  1. For Pre-AP only: Which pair of graphs represents the same motion of an object?
