Q. The 200.g head of a golf club moves at 40 m/s in a circular ARC of 1.2 m radius. How much force must the player exert on the handle of the club to prevent it from flying out of her hands at the bottom of the swing? Ignore the mass of the club's shaft.
Q. A 14 N horizontal force pushes a block weighing 5.4 N against a vertical wall. The coefficient of static friction between the wall and the block is 0.59, and the coefficient of kinetic friction is 0.35. Assume that the block is not moving initially. In unit-vector notation (Fx i + Fy j), what is the force on the block from the wall?
