Question

A force of 80N acting on q certain mass for 3second gives a velocity of 6m/s .Find the mass of the body if the body was initially at rest​

Answer 1

hope it will helps you... .

Answer 2

given

force = 80N

time = 3s

velocity = 6m/s

initial velocity = 0

Find

acceleration = ?

we know that

=>v = u + at

=>v = at

=>a = v/t

=>a = (6m/s )/3s

=>a = 6m/s^2

Again

we know that

=>F = m*a

=>m = F/a

=>m = 80/6 kg

=>m = 40/3kg

=>m = 13.333'kg

Formula keep in mind

• v = u + at
• force = mass * acceleration
