And explain why.
Also..formula for inelastic collision is..
M(a)V(a)+M(b)V(b)=M(a)V(a2)+M(b)V(b2)?
And elastic is..
M(1)V=M(1)V(1)+M(2)V(2)
?

Here on earth, water appears to be incompressible. We are told that black holes exist in space; these have enormous density so much so that whole solar systems collapse on themselves until they occupy a space no larger than pea. When do the laws of physics change and the apparently incompressible substances start to shrink?

Explain:
Whether the photons emitted by a bright light bulb are more energetic than those emitted by a dim light bulb of the same color. How does the color of the light bulbs determine the amount of energy of the electromagnetic waves?!

Starting with an initial speed of 5.00 m/s at a height of 0.300 m, a
1.50-kg ball swings downward and strikes a 4.60-kg ball that is at rest, as the drawing shows. (a)
Using the principle of conservation of mechanical energy, find the speed of the 1.50-kg ball just
before impact. (b) Assuming that the collision is elastic, find the velocities (magnitude and
direction) of both balls just after the collision. (c) How high does each ball swing after the
collision, ignoring air resistance?

Please show work! (:

Jill has just gotten out of her car in the grocery store parking lot. The parking lot is on a hill and is tilted 3 degrees. Fifty meters downhill from Jill, a little old lady lets go of a fully loaded shopping cart. The cart, with frictionless wheels, starts to roll straight downhill. Jill immediately starts to sprint after the cart with her top acceleration of 2.0m/s^2.
How far has the cart rolled before Jill catches it?

Problem 6.65
You have been hired to assist with stunts for a new action movie. In one scene, the writers want to drop a package from a small plane into a moving convertible sports car. The car will drive along a horizontal road at 30.0 m/s. The plane will approach the car from behind at an altitude of 60.0 m and a speed of 90.0 m/s relative to the ground. The copilot will view the car through a sighting tube that measures the angle below horizontal.

At what angle should the package be released? degrees below the horizontal

Why does a car need higher torque to run over a higher inclination...

Why we need higher gear..

Energy: Torque*angular velocity
When we vary the torque using gears the speeed decreases and theoretically..the energy remains the same...

Now if we are providing the same energy why we cannot do the same thing with it?

I am having trouble with this momentum question..

The momentum of an apple falling to the ground is not conserved because the external force of gravity acts on it. But the momentum is conserved in a larger system. Explain how.

Movies show people being slammed backwards by bullets hitting them. Never mind that it's not realistic, the question is, if bullet catridges are going to have a certain amount of gunpowder, which will have more "knock-down" power, heavier or lighter bullets? Lighter bullets will have a higher muzzle velocity, but heavier bullets have more momentum.
