1. A paper ball is flicked off a 1.5-m tall table at a 20 angle from the horizontal with a speed of 5.0 m/s.

(A) What is the horizontal speed of the paper ball?

(B) The box slides into a spring with a spring constant of 100 N/m, compressing the spring and bringing the box to a stop. What energy transformation took place?

2. Two forces are acting on an 5.0-kg object as shown below.

F1 F2B V = Isng / K= LOON m 8 kq + Initial Situation K= 10OW m Final situation The Energy transformation that takes place is, kinetic energy converted to Spring Energy
