Q1. An archer puts a 0.54 kg arrow to the bowstring. An average force of 202 N is exerted to draw the string back 1.3 m. suppose that air resistance is negligible.

Q2. An air puck of mass of 0.024 kg is tired to a string and allowed to revolve in a circle of radius 1.3m on a frictionless horizontal surface. The other end of a string passes through a hole in the center of the surface, and mass of 1.1 kg is tired to it. The suspended mass remains in equilibrium even as the puck reviles on the surface. What is the magnitude of the force that maintains circular motion acting on the puck?
