2. 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/s, one second after the car passes the signage. How long does it the police officer to overtake the truck?

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?

1. Assuming no air resistance, if the time for a projectile to get to the highest point is 27s, what would be its total flight time (in s)? 2. An object that has been moving with a speed of 5m/s for 10s can have a zero displacement. YES OR NO? 3. A person drops a stone from the top of a bridge that is 28.6m high. How long (in s) will it take the stone to hit the water?
Person A is waiting patiently at a traffic light when person B zooms past him at 25.5m/s^2. after 1.4s, person A's car accelerates at a rate of 4.5m/s^2 . Will person A be able to catch up to person B? If so how long? If not, how close will person A get to person B?
Why is the following situation impossible? A freight train is lumbering along at a constant speed of 16.0 m/s. Behind the freight train on the same track is a passenger train traveling in the same direction at 40.0 m/s. When the front of the passenger train is 58.5 m from the back of the freight train, the engineer on the passenger train recognizes the danger and hits the brakes of his train, causing the train to move with acceleration 3.00 m/s2. Because of the engineers action, the trains do not collide.
1) A car traveling 97 km/h is 280 m behind a truck traveling 79 km/h. How long will it take the car to reach the truck? .2)At highway speeds, a particular automobile is capable of an acceleration of about 1.8 m/s2 At this rate, how long does it take to accelerate from 75 km/h to 130 km/h ? 3) A ball player catches a ball 3.26 s after throwing it vertically upward. part a) With what speed did he throw it? part b) What height did it reach? Express your answer to three significant figures and include the appropriate units. 4)A falling stone takes Δt = 0.26 s to travel past a window 2.2 m tall From what height above the top of the window did the stone fall? Express your answer to two significant figures and include the appropriate units.
11. the car has an initial speed of 20 m/s and an acceleration of -1m/s^2. Find the displacement ( m) after the first 10 seconds? 9. If you are driving 110km/h along a straight road and you look to the side for 2.00s how far (dm) do you travel during this inattentive period?
Suppose that a person unwisely drives 75 mi/h in a zone 55 mi/h and passes a police car going 55 mi/h in the same direction. If the police officers begin constant acceleration at the instant they are passed and increase their velocity to 80 mi/h in 4 s, how long does it take them to be even with the pursued car? Ans. 10s
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?
At the instant the traffic light turns green, a car that has been waiting at an intersection starts ahead with a constant acceleration of 3.20 m/s^2. At the same instant a truck, travelling with a constant speed of 20.0 m/s, overtakes and passes the car. How far (in m) beyond its starting points does the car overtake the truck?
