A particle of mass 15 kg has an intitial velocity vi= i cap -2 j cap m/s. It collides with another body and the impact time is 0.1 sec, resulting in a velocity vf= 6 i cap + 4 j cap + 5 k cap m/s after impact. The average force of impact on particle is????....kindly answer as soon as possible..u can also write only the answer

Dear student

F = dP / dt

F = m [V_f- Vi] /t = 15 [(6i + 4j +5k) - (1i - 2j)] /0.1

=15 [ 5i +6j +5k] /0.1

=150 (86)^1/2 =150*9.27=1391 J
