Q. A bowling ball with a mass of 6.8 kg strikes a stationary pin that has a mass of 1.6 kg. After the collision, the pin flies forward (in the positive x direction) with a velocity of 7.3 m/s, and the ball continues forward at 3.2 m/s (in the positive x direction). What was the original velocity of the ball? How do you solve this?
Q. A certain star is 10.6 light years away. How long would it take a spacecraft traveling 0.960c to reach that star from earth, as measured by observers:(a) on Earth(b) on the spacecraft(c) What is the distance traveled according to observers on the spacecraft(d) What will the spacecraft occupants compute their speed to be from the results of (b) and (c)?
A box is hanging from a chain having a mass of 60 kg. The box has a mass of 78 kg. Find the tension in the top of chain and the bottom of the chain.
Calculate the total cost ($/kWh) of electricity delivered to the grid including fuel cost and debt charge with O&M of 5% added to the total.
For instance, the flute can be described as an open-open pipe because a flutist covers the mouthpiece of flute only partially. Meanwhile, a clarinet can be described as an open-closed pipe as the mouthpiece of the clarinet is almost completely closed..
Now a peg is placed 4/5 of the way down pendulum's path so that when the mass falls to its vertical position it hits and wraps around the peg. As it wraps around the peg and attains its maximum height it ends a distance of 3/5 L below its starting po..

A toy train is pushed forward and released at xi = 1.60 m with a speed of 2.60 m/s. It rolls at a steady speed for 1.30 s, and then one wheel begins to stick. The train comes to a stop 6m from its starting point. What is the train's acceleration a..
A dynamite blast at a quarry launches a rock straight upward, and later it is rising at a rate of 15m/s. Assuming air resistance has no effect on the rock, calculate the total time the rock is in the air.
A loudspeaker on a tall pole broadcasts sound waves equally in all directions. If the sound output is 7.0 W, at what distance from loudspeaker is the sound intensity level 85.7 dB.
A 25- sample of an ideal gas with is at 250 and 50. The gas is compressed isothermally to one-third of its original volume, then heated at constant volume until its state lies on the adiabatic curve that passes through its original state, and then al..
1.76- block at rest on a ramp of height. While the block is released, it slides without friction to the bottom of the ramp, and then continues across a surface that is frictionless except for a rough patch of width 12.0 that has a coefficient of kine..
