A cart of mass m1=10 kg slides down a frictionless ramp and is made to collide with a second mass m2=20kg, which then heads into a perpendicular loop of radius .25m. The carts stick together after the collision. Discover the height h from which cart 1 would need to start to make sure that both carts complete the loop without leaving the track. Also find the height needed if instead the more massive cart is made to collide with the smaller cart.
Your dog is running around the grass in your back yard. He undergoes successive displacements 3.37 m south, 8.45 m northeast, and 13.3 m west. What is the resultant displacement?
