At a football tryout, a player runs a 40-yard dash in t₂ = 4.15 seconds. If the reaches his maximum speed at the 15-yard mark L₁ with a constant acceleration and then maintains that speed for the remainder of the run, determine his acceleration over the first 15 yards, his maximum speed, and the time duration of the acceleration.

Find the time for the patrolman to reach a maximum permissible speed of 150 kph. b. How long did it take the patrolman to overtake the car from the time he starts from A.? c. Calculate the distance S from point A to the point at which he overtakes the car.
The brakes of a car are applied, causing it to slow down at a rate of 10 ft/s2. Knowing that the car stops 300 ft, determine (a) how fast the car was traveling immediately before brakes were applied, (b) the time required for the car to stop.

3. Two cars A and B travelling in the same direction and stopped at a highway traffic sign. As the signal turns green car A accelerates at a constant rate of 1m/s2. Two seconds later the second car B accelerates at constant rate of 1.3m/s2. When will the second car B overtakes the first car A.
A motorcyclist at A is traveling at 60 ft/s when he wishes to pass the truck T which is traveling at a constant speed of 60 ft/s. To do so the motorcyclist accelerates at a = 6 ft/s^2 until reaching a maximum speed of 85 ft/s If he then maintains this speed, determine the time needed for him to reach a point located 100 ft in front of the truck. Draw the v-t and s-t graphs for the motorcycle during this time.
it takes about 3 s for a driver having 0.1% alcohol in his system to react to a situation to avoid a collision. if such drivers are traveling on a straight road at 40.11ft/s and their cars can decelerate at 2.714ft/s^2, determine the shortest stopping distance d (in feet) from the moment they see the pedestrians.

You are to determine the duration of the yellow light at a highway intersection. Assume that cars will be approaching the intersection traveling at 70 mph, and that the reaction time of the driver is 2.5 sec and that cars achieve a deceleration of 1/8 of the gravitational acceleration. if g=32.2 fps^2, a. how long must the traffic light remain yellow to allow drivers to come to stop before the traffic light turns red? b. what is the minimum distance of a car from the intersection when the lightturns yellow to ensure that it comes to a full stop before the intersection?
A car starts from rest and travels 10 sec. with an acceleration of a = 4 – 0.3t, then runs for 30 sec. at constant velocity and finally comes to rest by decelerating at 3.125 m/s2.
