Problem 5PE

A runaway train car that has a mass of 15,000 kg travels at a speed of 5.4 m/s down a track. Compute the time required for a force of 1500 N to bring the car to rest.

Step-by-Step Solution:

Step-by-step solution In this problem example of an runaway train car moving with certain given velocity is given so,explain the following given condition and find the time required for a certain force to bring the car to rest as per the given data respectively: Step 1 of 6 The formula to find the net force is, Here is the change in speed, is the change in time and is the net force, Step 2 of 6 The formula to find the change in speed is, The initial speed is, Now, the force has brought the car to rest. So, the final speed is, Step 3 of 6 Substitute for and for ,
