Question:A force of 10 Newton starts acting on a body kept at rest. Find the momentum of the body at 5 seconds after the four starts acting?__________________________________________________________Answer:Let ‘m’ be the mass of the body. The acceleration be ‘a’.F = ma

=> 10 = ma

=> a = 10/m

Initial velocity at t= 1 will be zeroVelocity after 1 s = at = 10/m Ns

Momentum after 1 s is, p1 = mv1 = m(10/m) = 10 Ns

Velocity after 5 s is, v5 = at = (10/m) x 5 = 50 Ns or 50 Kgm/sPlease mark me brainliest
