Transcribed Image Text:*13-20. 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 Hi = 0.3,
determine the speed at which each crate slides off the ramp
at B. Assume that no tipping occurs. Take 0 = 30°.
