A motocross racer hits a checkpoint 25 s into a race that is 320 m [E] from the starting point. At the checkpoint, the racer takes a sharp turn, and at 49 s into the race hits another checkpoint that us 140 m [W) from the starting line. What is the average velocity of the racer between the two checkpoints? (1.2)

At a stop light, a truck travelling at 15 m/s passes a car as it starts from rest. The truck travels as constant velocity and the car accelerates at 3 m/s^2. How much time does the car take to catch up to the truck? a. 25 s b. 20 s c. 15 s d. 10 s e. 5 s Starting at time t = 0, an object moves along a straight line. Its coordinate in meters is given...

A cyclist sprints at the end of a race to clinch a victory. She has an initial velocity of 11.3 m/s and accelerates at a rate of 0.610 m/s for 7.85 s. (a) What is her final velocity? (Enter the magnitude in m/s.) 16.089 m/s (b) The cyclist continues at this velocity to the finish line. If she is 300 m from the finish line when she starts to accelerate, how much time did she save (in s)? (c) The...

A car on a straight flat road races a boat on calm canal parallel to the road. The car has a constant acceleration of 1.95 m/s and reaches a top speed of 41.0 m/s. The boat has a constant 2 acceleration of 6.50 m/s and reaches a top speed of 32.0 m/s. The car and the boat accelerate to 2 their top speeds and then maintain their top speeds for the remainder of the race. They race for 1.20 km....

1)Two boats start together and race across a 48-km-wide lake and back. Boat A goes across at 48 km/h and returns at 48 km/h. Boat B goes across at 24 km/h, and its crew, realizing how far behind it is getting, returns at 72 km/h. Turnaround times are negligible, and the boat that completes the round trip first wins. A) By how much? B)What is the average velocity of the winning boat? 2)A race car moves such that its position...

4. (7 pts) A car is travelling with constant speed down the highway at 33.5 m/s. At the instant this car passes an entrance ramp, a second car enters the highway, starting from zero at the beginning of the ramp. What constant acceleration must the second car have in order to catch the first car in 2.50 km?

A4 kg block travelling with velocity VB = 6 m/s collides with a wall. As a result of the collision, the direction and magnitude of the velocity of the block has changed and the block is travelling with velocity VA = 2 m/s. What is the magnitude of the average force (in N) exerted by the wall on the block if the block was in contact with the wall for 0.008 s? VB VA Before After
