A car moves from traffic lights along a straight road with constant acceleration. The car starts from rest at the traffic lights and 30 second later the car passes a speed-trap where it is registered as travelling at 45 Km/h. Find the acceleration of the car, b the distance between the traffic lights and the speed-trap.

If the brakes supply a constant deceleration of 22 ft/s2, determine: the expressions for the truck’s velocity v and position c at anytime t how long will it take to stop? how far does the car travel before coming to a complete stop?
A UCI student is running at her top speed of 5.1 m/s to catch a Shuttle bus, which is stopped at the bus stop. When the student is still a distance 42.0 m from the Shuttle bus, it starts to pull away, moving with a constant acceleration of 0.163 m/s2 .For how much time does the student have to run at 5.1 m/s before she overtakes the bus?
At t=0, a car registers at 30 miles/hr. Forty seconds later, the car’s velocity is now at 50 miles/hr. Assuming constant acceleration, find the value of his acceleration.
A UCI student is running at her top speed of 5.1 m/s to catch a Shuttle bus, which is stopped at the bus stop. When the student is still a distance 42.0 m from the Shuttle bus, it starts to pull away, moving with a constant acceleration of 0.163 m/s2. For what distance does the student have to run at 5.1 m/s before she overtakes the bus?
A blue car is moving at a constant speed of 70 m/s when it passes signage with a police officer beside it. Due to the car's over speeding, the police officer chases it with a constant acceleration of 4 m/s2, one second after the car passes the signage. How long does it the police officer to overtake the truck?
A driver is traveling 18.0 m/s when she sees a red light ahead. Her car is capable of decelerating at a rate of 3.65m / (s ^ 2) If it takes her 0.380 s to get the brakes on and she is 24.0 m from the intersection when she sees the light, will she be able to stop in time? How far from the beginning of the intersection will she be, and in which direction?
A police car is traveling at a velocity of 16.0 m/s due north, when a car zooms by at a constant speed of 50 m/s due north. After a reaction time of 0.700 s the policeman begins to pursue the speeder with an acceleration of 5.00 m/s2. Including the reaction time, how long does it take for the police car to catch up with the speeder?
