A hockey ball of mass 200 g travelling at 10 m s is strucka hockey stick so as to return it along its original path with avelocity at 5 ms. Calculate the change of momentum occurredin the motion of the hockey ball by the force applied by thehockey stick.13.by |

Answer» Mass = 200g = 0.2kginitial velocity (u)= 10 m/s^2final Velocity (v)= 5 m/s^2 Now to Find change in momentum: Change in momentum(p)= m(v-u) = 0.2(10-5) = 0.2 x 5 = 1 kg m/sec✓ the change in momentum occured in the motion of the hockey ball by the force applied by the hockey stick is 1 kg m/s |
