Uniformly Accelerated Motion

Directions: On this worksheet you will practice solving problems by using the five basic kinematics equations for uniformly accelerated motion.

Question 1  Scenario #1: A car accelerates uniformly from rest to a final speed of 24 m/sec in 11 seconds. How far does it travel during this period of acceleration?
Question 2  What acceleration did the car is Question 1 experience?
Question 3  Scenario #2: A pickup truck moving at 30 m/sec must come to a stop in a distance of 203 meters to avoid hitting a boulder that has fallen onto the road. How much time does the driver have to avoid an accident?
Question 4  What acceleration did the truck experience in Question 2?
Question 5  Scenario #3: A row boat, starting from rest, takes 11 seconds to travel 30 meters. If the boat maintains a uniform acceleration, what will be its instantaneous velocity at the end of this intial 11-second period?
Question 6  At the point in the stream where the boat in Question 5 is crossing, the stream is a total of 203 meters wide. If the boat continues maintaining the final velocity it achieves at the end of 11 seconds for the remainder of the trip, how much total time will it need to reach the opposite shore?
Question 7  What acceleration did the row boat initially experience in Question 5?
Question 8  Scenario #4: A go-cart, accelerating down a hill at 2.75 m/sec2 can travel 79 meters in 7.5 seconds. What was the cart's initial velocity at the top of the hill after a subtle, not so official, push-start?
Question 9  What was the cart's final velocity when it reached the bottom of the hill?
