Question

A ball of mass 100 grams is hit by a hockey stick giving an impulse of 0.083 Newton, with what velocity does the ball move

Answer 1

Mass of the ball,

100g=0.1kg

Impulse=0.083Ns

We know,

Impulse=change in momentum

So,

I=m(v-u)

0.083=0.1(v-0)

0.083/0.1=v

0.83m/s=v

Hope it’ll help

Answer 2

Hii dear,

You have given unit of impulse as N. It should be N.s

# Impulse-
Impulse is a vector quantity defined as the product of the force acting on a body and the time interval during which the force is exerted.
The SI unit of impulse is Newton-second (N.s).

# Given-
I=0.083N.s
u=0m/s
m=100g=0.kg

# Formula-
Impulse is given by formula,
Impulse = change in momentum
Impulse = mass (final velocity-initial velocity)
I = m(v-u)

Putting values
0.083 = 0.1 (v-0)
v = 0.83m/s

Ball will move with velocity 0.83m/s.
