Suppose a person standing on the top of a building of 160 ft high throws a ball directly upward with an initial speed of 48 ft/s. a. find the ball's height, velocity and acceleration at time t. b. when does the ball hit the ground and what is its impact velocity? c. how far does the ball travel during its fligh

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.)

The pressure proportional to the area a- inversely b- directly c- increase d-decrease

Abicycle slows down when the rider applies the brakes. what type of energy transformation is involved in this example? a. kinetic energy into heat energy b. heat energy into potential energy c. potential energy into kinetic energy d. kinetic energy into mechanical energy
