A ball is projected upward at time = 0.0 s, from a point on a roof 30 m above the ground. The ball rises, then falls and strikes the ground. The initial velocity of the ball is Consider all quantiti
When the block is pulled out to x = +4.0 cm, we must apply a force of magnitude 370 N to hold it there. We pull the block to x = 14.0 cm and then release it. How much work does the spring do on the
You're carrying a 4.0-m-long, 24 pole to a construction site when you decide to stop for a rest. You place one end of the pole on a fence post and hold the other end of the pole 35 from its tip. How
A wave is described by y = (2.00 cm) sin(kx - t), where k = 2.11 rad/m, = 3.62 rad/s, x is in meters, and t is in seconds. Determine the amplitude, wavelength, frequency, and speed of the wave.
