Question

A force with a magnitude of 452 N is used to stop an object with a mass of 56.0 kg moving at a velocity of 155 m/s. How long will it take to bring the object to a full stop?

Answer 1

Time, t = 19.20 seconds.

Step-by-step explanation:

Given the following data;

Force = 452N

Velocity = 155m/s

Mass = 56kg

To find the time;

`Force = \frac {mass * velocity}{time}`

Substituting into the equation, we have;

`452 = \frac {56 * 155}{time}`

Cross-multiplying, we have

`452t = 8680`

`Time, \; t = \frac {8680}{452}`

Time, t = 19.20 seconds.
