Question

If a force of 60 n acts on a body for interval of 0.5 s then the impulse is

Answer 1

Impulse is nothing but change in momentum or force applied in a certain time ,given as

J(impulse)=dF/dt

So,given

F=60N

dt=0.5s

J=60/0.5

J=120 N s

Answer 2

The impulse of the body is 30 kg-m/s.

Explanation:

Given that,

The force acting on the body, F = 60 N

Time, t = 0.5 s

To find,

Impulse

Solution,

Impulse of an object is called as the impact of force. It is given by the product of force and time as :

$J=Ft$

$J=60\ N\times 0.5\ s$

J = 30 kg-m/s

So, the impulse of the body is 30 kg-m/s.
