In the system shown below mi = 16.0 kg and the plane is inclined at a = 53.0. The coefficient of kinetic friction between the block and the incline is Hk = 0.30. What must be the value of the mass m2 of the hanging block if it is to move straight downward a distance of 8.00 meters in the first 2.00 seconds after the system is released from rest? {There is no friction between the string and the pulley. The string is very long and does not stretch. The hanging block does not strike the floor either.}
