The m = 50000 lbm flatcar B supports a cart mg= 10000 lbm. The crate is on rollers on a 0 = 10°
ramp built on the flatcar. The crate is released from rest at time tị with the flatcar also at rest. Just
before hitting the stop at the left-hand side, the time is t2. The distance down the ramp s12 = 40 ft, and
the relative speed of the flatcar just before impact is (VB/A)2= 4 f/s. Neglect all friction and treat the
crate and the flatcar as particles.
