An average force of 100N acts on a body for 1s. What is the impulse due to the force?
100 Ns
0.1 Ns
100000 Ns
10 Ns
Impulse =F Δt = 100 x 1 = 100 Ns
A constant force,→F=2^i+2^j acts on a body of mass 2 kg due to which the body gets displaced from (0,0,0) to (5,0,0). What is the work done by this force?
Due to an impulse, the change in momentum of a body is 1.8 kg ms−1. How much is the force acted on it if the duration of the force acting is 0.2 s ?
