Askydiver is falling at constant velocity. if a force of 600 n is pulling down on the skydiver, how much force must be acting upward on the skydiver?

exactly 600 n
slightly more than 600 n
slightly less than 600 n
exactly 0 n

In what direction does an applied force move an object? in the same direction as the force independent of the force in the opposite direction of the force perpendicular to the force

Aspring with a mass of 2 kg has a damping constant 14 kg/s. a force of 3.6 n is required to keep the spring stretched 0.3 m beyond its natural length. the spring is stretched 0.6 m beyond its natural length and then released. find the position of the mass at any time t. (assume that movement to the right is the positive x-direction and the spring is attached to a wall at the left end.)
