A runaway train car that has a mass of 1.550×104kg travels at a speed of 5.35m/s down a track. Compute the time required for a force of 1.50×103N to bring the car to rest.

55.15 sec.

Explanation:

Given that the force = N

We know, Force = mass × acceleration

So,

Acceleration = is the negative acceleration produced by the force.

Now, using formula

As the car finally stops so will be zero.

So,

Thus, = 55.15 sec.

So, the time required for the force to bring the car to rest will be 55.15 seconds.
