What is the velocity of a shot put with a mass of 7.3 kg and momentum of 22 kg -m/s moving in the forward direction?
How much potential energy does a car gain if a crane lifts the car with a mass of 1,500 kg and 20 m straight up
Imagine that you are on a space walk outside a vessel coasting
through interstellar space. You have launched a reference probe that is
perfectly stationary relative to the ship, equipped with precision laser
velocity-measuring devices. A meteoroid approaches at 4.0 m/s, strikes
the ship, and bounces off in exactly the opposite direction at 2.0 m/s.
you grab the meteoroid, take it into the ship, put it into an inertial mass
meter, and find out that it masses 1.0 kg. The ship’s mass is 20,000 kg
without you on board. You know that the impact has caused the space
ship to start moving relative to the probe in the same direction the
meteoroid was originally travelling. What will the probe indicate as the
magnitude of the ship’s post-collision velocity vector?
Peng Nepomuceno, a world renowned bowler holds a 12 pound bowling ball that is held 5 ft above the floor. A.) Calculate the GPE of the bowling ball. B.) If the crate were lifted by a crane to a height of 25m, how much work is done?

If you lift a box using a 100 J of work within 5 s, how much power has been done? How much is the power if it’s lifted using a 10 J of work?
List all the forces that act on you while you are standing on the ground.
Diagram/Sketch the forces.
Suppose two lumps of clay approach each other from opposite
directions in deep space. Lump number 1 masses 4.00 kg and travels at
5.00 m/s. Lump number 2 masses 10.0 kg. When the lumps collide, no
material flies off. The lumps stick together , and the resulting object is
stationary relative to you, the observer. How fast was lump number 2
moving before the collision relative to you, the observer?
Two asteroid s are drifting away from each other.One asteroid have mass of 240000 kg. and the other has a mass of 100000 kg. What is the change in gravitational potential energy as their center s of the mass move from 100 m apart to 1000 m apart?
the 50-kg, uniform crate slides down the inclined surface with an initial speed 10 m/s. if the coefficient of kinetic friction between the crate and the inclined surface is 0.15, determine the distance s the crate has moved when it momentarily stops. (Assume tipping over does not happen)
