Question

A force of 100N acts on a. mass of 25 kg for 5seconds.what velocity does it generates.​

Answer 1

Explanation:

Force=f=100N

Mass=m=25kg

Time=t=5 sec

by formula

F =ma

a=f/m

a= 100/25

a=4 m/s^2

V=u+at

v=0+4(5)

v=0+20

v=20m/s

hence Velocity =20m/s

I hope it will help you

Answer 2

Answer

20 m/s

_________________

Given

F = 100 N

m = 25 kg

_________________

To find

Velocity generated

_______________

Steps

According to Newton's second law

F=ma

Putting in the equation

⇝100=25×a

on solving

⇢a=4ms

−2

Now the body initially is stationary therefore initial velocity (u) must be zero

u = 0

Applying Newton 1st Law of Motion

V = U + AT

Substituting the values to find final velocity at t= 5 sec

⇝v=0+4×5

⇢v=20m/s

Hence, the final velocity is 20 m/s
