The baggage truck A shown in the photo below has a weight of 900 lb and tows a 550-lb cart B and 325lb cart C. For a short time the driving frictional force developed at the wheels of the truck is 40t lb,where t is in seconds. If the truck starts from rest, determine its speed in 2 seconds. Also, what is thehorizontal force acting on the coupling between the truck and the cart B at this instant?
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.
