Questions
A man is raising himself and the crate on which he stands with an acceleration of 5 by a massless rope-and pulley arrangement. Mass of the man is 100 kg and that of the crate is 50 kg. If g = 10 , the contact force between man and the crate is
detailed solution
Correct option is D
m1 = 100 kg, m2 = 50 kg, a = 5 m/s2 T + N -m1g = m1aT-N - m2g = m2aSolving these:T = 1125 N andN = 375 NTalk to our academic expert!
