Question

a body of mass 10 kg is moving with a velocity of 125 metre/s find the force needed to stop it in 4 seconds​

Answer 1

Answer:

mass of body : 10kg

velocity : 125 meter/s^2

time : 4 second

We now that

acceleration (f) = velocity/time

acceleration (f ) = 125/4 (division)

acceleration (f) =31.25 m/s^2

now, froce (p) = mass × acceleration

= 10kg × 31.25m/s^2

312.5 N(Newton) . answer
