n undamped 1.47-kg horizontal spring oscillator has a spring constant of 25.1 N/m. While oscillating, it is found to have a speed of 3.17 m/s as it passes through its equilibrium position. What is its amplitude of oscillation? What is the oscillator\'s total mechanical energy as it passes through a position that is 0.651 of the amplitude away from the equilibrium position?
A 4.5kg dog stands on an 18 kg flatboat at distance D = 6.10m from the shore. It walks 2.4 m along the boat toward shore and then stops. Assuming no friction between the boat and the water, find how far the dog is then from the shore.
Find out distance the two drivers travel
A major-league catcher gloves a 85 mi/h pitch and brings it to rest in 0.17m. If the force exerted by the catcher is 803 N, what is the mass of the ball.
A test rocket is fired vertically upward from a well. A catapult gives it an initial speed of 80.6m/s at ground level. Its engines then fire and it accelerates upward at 3.80 m/s2 until it reaches an altitude of 930m. At that point its engines fai..
