Question

an object has a mass of 13g, starts from rest and experiences a change in velocity of 7m/s ,what is the value of the impulse experienced by the object ?

Answer 1

• Given :

=> mass (m) = 13 g = 0.013 kg

=> change in velocity (dV) = 7 m/s

• Explanation :

Accoding Netwon's second law of motion..

Impulse = Change in momentum

F * dt = dP = m * dV

So, Impulse = m * dV

Here, m = mass of moving object

dV = change in velocity

Thus, Impulse = 0.013 * 7 = 0.091 kg * m / s

• Answer :

Impulse = 0.091 kg*m/s
