A 0.150kg toy is undergoing SHM on the end of a horizontalspring with a force constant 300 N/m. When the object is 0.0120mfrom its equilibrium position, it has a speed of 0.300 m/s. Find
a) the total energy of the object at any point in its motionand
b) the maximum speed attained by the object duringits motion.
When a parachute opens, the air exerts a large drag force on it.This upward force is initially greater than the weight of the skydiver and, thus, slows him down. Suppose the weight of the skydiver is 902 N and the drag force has amagnitude of 1030..
