1. A cart of mass m = 10 kg slides down a frictionless ramp and is made to collide with a second cart (initially at rest of mass m2 20 kg, which then heads into a vertical loop of radius 0.25 m as shown in Figure P7.66. Derive the expression of height h. in terms of radius r, from which cart 1 would need to start to make sure that cart 2 completes the loop without leaving the track and hence determine the value of h. Assume an elastic collision

i guess it’s a and b

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.
