An arrow is fire with a speed of 20m/s at the block of Styrofoam resting on a smooth surface. The arrow penetrates a certain distance into the block before coming to rest relative to it.
Assume that the partner moves on a circle that has a radius of 6.50 m. At a swinging speed of 4.45 m/s, what force must the man apply to his partner in the straight-down position?
A block of mass 4.0 kg is put on top of a block of mass M = 5.5 kg. To cause the top block to slip on the bottom one, while the bottom one is held fixed, a horizontal force of at least 16 N must be applied to the top block. The assembly of blocks is ..
