A horse is running across a field. The horse accelerates at 2.00 m/s2 over a distance of 6.70 m. It runs until its speed is 17.6 m/s and continues at this speed. What was the horse's initial speed?

A speedboat starts from rest and accelerates at +2.31 m/s2 for 6.98 s. At the end of this time, the boat continues for an additional 6.40 s with an acceleration of +0.758 m/s2. Following this, the boat accelerates at -0.667 m/s2 for 6.68 s. (a) What is the velocity of the boat at t = 20.06 s? (b) Find the total displacement of the boat.

One simple model for a person running the 100 mm dash is to assume the sprinter runs with constant acceleration until reaching top speed, then maintains that speed through the finish line.     If a sprinter reaches his top speed of 11.1 m/sm/s in 2.44 ss , what will be his total time?

A car is 12 m from the bottom of a ramp that is 8.0m long at its base and 6.0m high at its tallest. The car moves from rest toward the ramp with an acceleration of magnitude 2.5 m/s?. At some instant after the car starts moving, a crate is released from rest from some position along the ramp. The crate and car reach the bottom of the ramp at the same moment and traveling at the same speed. The crate accelerates along the ramp at a rate of 5.88 m/s². 2.5 m/s? 6.0 m 8.0 m 12 m 2015 Pearson Education InG Draw a pictorial representation first (Tactics Box 1.5). Refer to the Problem Solving Strategies (General Pg21 and 2.1, 4.1) and Models 2.1, 2.2, and 4.1 for best Problem Solving Strategies. Hint: Use two different coordinate systems for the car (x) and the crate (s). A. What is the speed of the car when it reaches the base of the ramp? B. What is the distance, d up the ramp, at which the crate was released? C. How many seconds after the car started was the crate released?

You throw a ball straight up with an initial velocity of 15.9 m/s. On the way up it passes a tree branch at a height of 6.6 m.How much additional time will pass before the ball passes the tree branch on the way back down?

A cat is being chased by a dog. Both are running in a straight line at constant speeds. The cat has a head start of 3.8 m. The dog is running with a speed of 9.1 m/s and catches the cat after 6.6 s. How fast did the cat run? m/s

A typical sneeze expels material at a maximum speed of 58.6 m/s. Suppose the material begins inside the nose at rest, 2.00 cm from the nostrils. It has a constant acceleration for the first 0.250 cm and then moves at constant velocity for the remainder of the distance. What is the acceleration as the material moves the first 0.250 cm  (0.250 m)?

You are standing on a circular track that is 315 m long. You begin jogging at the start line and keep jogging until you complete one full lap and stop at the same point you started at. - What is the total distance you travel?  - What is your final displacement?    A world class sprinter ran 200 m in 21.75s. What was her average speed? (m/s)

Compute your  Average velocity in the following two cases: (a)  You walk 61.4 m at a speed of 2.47 m/s and then run 61.4 m at a speed of 3.34 m/s along a straight track. (B)  You walk for 1 minute at a speed of 2.47 m/s and then run for 1.8 minutes at 3.34 m/s along a straight track

A drag racer starts from rest and accelerates at 10.0 m/s2 for the entire distance of 300 m. What is the velocity of the race car at the end of the run?
