Question

An object mass 5kg is moving with a velocity of 10m/s​

Answer 1

Answer:

A body of mass 5kg is moving with a velocity of 10m/s. What will be the force required to stop it in 2 seconds?

Productivity maximized.

Given Data:-

mass= 5kg

Initial velocity= 10 m persecond

Final Velocity= 0

Time= 2s

Required:-

F=?

Solution:-

First of all. To find acceleration we use first equation of motion.

a= vf - vi/ t

a= -5 m persecond square

Now Using Newton's second law of motion.

F= ma

F= -25N. The negative sign indicate that the force required to stop the body would be opposite to direction of the body.
