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.
Suppose that a projectile which is subject to a linear resistive force is thrown vertically down with a speed Vyo which is greater than the terminal speed Vterm. Describe and explain how the velocity varies with time and make a plot of Vy against t f..
