Logan jumps out of an airplane with a 7.0 kg parachute. After he opens the chute, he falls at a constant 5.6 m/s. Assume that Logan's mass is 70 kg.
A. Find the force of the parachute on Logan

Asolid cylinder and a cylindrical shell have the same mass, same radius, and turn on frictionless, horizontal axles. the cylindrical shell has light-weight spokes connecting the shell to the axle. a rope is wrapped around each cylinder and tied to blocks of equal masses that are held the same height above the ground. both blocks are released simultaneously. the ropes do not slip. which block hits the ground first? or is it a tie?
