an object of mass 10 kg is projected from ground with speed 40m/s at an angle 60degree with the horizontal . the rate of change of momentum of object one second after projection in SI unit is: a.73 b.98 c.170 d.140

Question

Hello · Answer

Rate of change of momentum = d(mv)/dt v = v horizontal + v vertical dv/dt = d(v horizontal + v vertical ) / dt = 0 + g (Since the only force acting is gravity downwards) Hence d(mv)/dt = m*g = 10*9.8 = 98
