A speeding car traveling at a constant velocity of 3.8 x 10'm/s passes a police car initially at rest beside the roadway. If the police car with constant acceleration of 3.4 immediately pursues the speeding car, how much time is it before the police car is directly behind the speeding car? answer in seconds. Answer:

A motorcycle starts from rest when t = 0 and travels along a straight road at a constant velocity of 7.0 ft/s² until it reaches a speed of 60 ft/s. Then it maintains this speed. Also, when t = 0, a car located 6000 ft from the motorcycle is traveling toward the motorcycle at a constant speed of 40 ft/s. Determine the time when they intersect.
5 2 A small steel ball, dropped from rest, takes 0.50 s to fall through a vertical distance of 1.25 m. Determine (a) the average speed of the ball, AVO Speed=DIT = 1.25/0.5 = 2.5mls (b) the actual speed of the ball after it has fallen through a vertical distance of 1.25 m, assuming that the acceleration is constant, the value of that acceleration. (c)
27. A driver of a car going 25.0 m/s suddenly notices a stop sign 40.0 m ahead. The braking deceleration rate of the car is 10.0 m/s², but it takes the driver 0.75 s (reaction time) to get the brakes applied. (a) Determine if the car runs the stop sign. (b) Determine the maximum initial speed at which the car could be moving and manage to stop at the sign.
A bus initially at a bus stop accelerates continuously for a kilometer, taking a minute and a half. Upon closing in on the next stop, the driver then begins to hit the brakes until it reaches a full stop in 8 seconds. Find the total distance that the bus traveled and the velocity of the bus just before it begins decelerating.
You are initially at rest in your car. At time t = 0, a truck passes you moving at 25.0 m/s. You thenimmediately begin to accelerate at 3.00 m/s^2 in the same direction the truck is moving. If youmaintain this acceleration, and the truck maintains its speed, when will you overtake the truck? Group of answer choices t = 5.00 s t = 16.7 s t = 2.50 s t = 25.0 s t = 8.33 s
A police car gets passed by a car traveling at a constant speed of 150.0 km/hr. The police car accelerates from rest at 5.00 m/s2, the moment the two cars are side by side. How long does it take the police officer to catch the car?
A car starts from rest with an acceleration of 7.2 m/s² which decreases linearly with time to zero in 9.6 seconds, after which the car continues at a constant speed. Determine the time t required for the car to travel 330 m from the start. Answer: t- i ! S
A Honda Jazz is stopped at a traffic light. It then travels along a straight road so that its distance from the light is given by x(t) = (2.4 m/s²)t² – (0.120) t³ a.
