A car is traveling to the right with a speed of 2.0m/s on an icy road when the brakes are applied. The car begins sliding with constant acceleration for 3.0m until it comes to a stop. How long does it take the car to slide to a stop?
Answer using a coordinate system where rightward is positive. Round the answer to two significant digits.
Homework Answers
U = 2.0m/s , V = 0 (stop) , S = 3m , t =?
From V^2 - U^2 = 2aS
=) a = -4/6 = -0.667m/s^2
Now again by V-U = at
We have t = -U/a = 2/0.667 = 3s
Hence require time is t = 3.0s

A car is traveling to the right with a speed of 29m/s when the rider slams on the accelerator to pass another car. The car passes in 110m with constant acceleration and reaches a speed of 34m/s. What was the acceleration of the car as it sped up? Answer using a coordinate system where rightward is positive. Round the answer to two significant digits.

A 1,200-kg car is traveling on an icy horizontal road at 30 m/s. The maximum rate at which the car can decelerate without sliding on the ice is 1.2 m/s2; reaching this value will immediately result in sliding uncontrollably with a reduced sliding friction of 700 N. If the driver panics and slams hard on the brakes, then how far will the car slide before stopping? Answer in km.

A car is traveling with a constant speed when the driver suddenly applies the brakes, giving the car a deceleration of 3.50m/s2. The car comes to a stop in a distance of 34.0 m. What was an initial speed of the car? How long (the time) did it take for this car to stop? What was the car's speed when it had traveled 17.0 m from the point where the brakes were applied? How long did it take for this...

A police car is traveling in a straight line with a constant speed "Vp". A truck traveling in the same direction with the speed "3*Vp/2" passes the police car. The truck begins to slow down (the moment it passes the police car) at a constant acceleration of "-a" until it comes to a stop. Then the police car passes the truck. What is the maximum velocity the truck can have, so that the police car will reach him before he...
