Question No 2 The conveyor belt delivers each 12-kg crate to the ramp at A such that the crate's speed is VA = 2.5 m/s, directed down along the ramp. If the coefficient of kinetic friction between each crate and the ramp is uk = 0.3, determine the speed at which each crate slides off the ramp at B. Assume that no tipping occurs. Take 0 = 30°. Calculate the speed if O = 60°. Is it greater or less? Why? VA = 2.5 m/s 区I 区 3 m 図

Question No 2
The conveyor belt delivers each 12-kg crate to the ramp at
A such that the crate's speed is VA = 2.5 m/s, directed down
along the ramp. If the coefficient of kinetic friction between
each crate and the ramp is µk = 0.3, determine the speed at
which each crate slides off the ramp at B. Assume that no
tipping occurs. Take 0 = 30°.
Calculate the speed if O = 60°. Is it greater or less? Why?
VA = 2.5 m/s
