The m = 50000 lbm flatcar B supports a cart mg= 10000 lbm. The crate is on i ramp built on the flatcar. The crate is released from rest at time tį with the flatca before hitting the stop at the left-hand side, the time is t2. The distance down the the relative speed of the flatcar just before impact is (VB/A)2= 4s. Neglect all crate and the flatcar as particles 15.1

A cart has a mass of 1.5 kg. It is given some initial push toward a sensor and is slowed by a hanging mass which makes the cart turn around and speed up as it returns to its original position. This situation is illustrated in the attached image. If the acceleration towards the sensor is 0.5 m/s2 and the accaleration away from the sensor is 0.15 m/s2,  a. draw the free body diagrams for the cart moving towards the sensor and away from the sensor. b. Write Newton's law for both situations and solve for the frictional force and for the force from the hanging mass.
