A ball of mass m is dropped at the same height as a second ball of mass 2m. The kinetic energy of the ball of mass m is less than the 2m ball when it strikes the ground. True Or False?

A ball with mass "m" at repose is hit by an other ball with mass "2m" that travels from the right at 1m/s , If after the collision the ball with mass "2m" continues to move right at 1/3 m/s a. does it conserve the total lineal momentum? why? b. Determine velocity (magnitude and direction) of the ball with mass "m" c. which type of collision is it?

The same constant force, F, is applied to two blocks. The first
block has a mass of M and the second block has a mass of 2M. Both
blocks are initially at rest and the force acts on each of them for
the same period of time, t.
15) After time, t, which block has
more momentum?
a)The block of mass M
b)The block of mass 2M
c)They will have the same momentum
16) After time, t, which block has
more kinetic...

Object A has a mass of m, object B has a mass of m/2, and object C has a mass of 2m. (a) If all three objects have the same momentum, rank them in order of increasing kinetic energy. (b)For the same three masses as before, now assume that the objects have the same kinetic energy, and rank them in order of increasing momentum.

(Assume there is no air resistance.) A ball of mass m and another ball of mass 3m are dropped. The two balls have the same kinetic energy when they hit the ground. If the ball of mass m was dropped from height h, the height of the ball of mass 3m dropped is h/3. Explain why.

A lacrosse ball and a tennis ball are approximately the same size, but the lacrosse ball has more mass. Using purely conceptual reasoning (do not rely on equations), apply the vector nature of momentum and the law of conservation of momentum to explain in your initial post to the discussion what happens when a lacrosse ball rolls into a resting tennis ball a tennis ball rolls into a resting lacrosse ball Think about the initial momentum vector and the fact...

8. There is a ball at rest in your reference frame with a mass M. A second ball also with the rest mass M is moving with speed v. The two balls collide, stick together, and continue on. Keep in mind that the combined mass after the collision will not be 2M. a. Write out the equation for conservation of relativistic momentum in terms of the initial and final speeds. b. Write out the equation for conservation of relativistic energy...

A red ball is dropped from rest at a height of 7.20 m. A blue ball at a height of 12.0 m is thrown down at the same instant at 7.00 m/s. How long does it take the blue ball to catch up with the red ball? Please show the formula used and show every step that way I can practice a bunch of other problems like this one. Thank you so much! <3

(b) At time n = 0, an urn contains 2m balls, of which m are red and m are blue. At each time n = 1, ..., 2m, a single ball is randomly selected and taken away with no replacement. Hence, at time n, the urn has 2m – n balls. Let Rn denotes the number of red balls remaining in the urn at time n. For n= 0,..., 2m – 1, let B Rn Pn = 2m - in...

a) A billiard ball at rest is struck by another billiard ball of the same mass whose speed is 6.0m/s. After an elastic collision the striking ball goes off at an angle of 25 degree with respect to its original direction of motion. Find the angle the struck ball makes with this direction and the final speeds of both balls. b) A particle of mass m, moving with a velocity u, makes a head on collision with a particle of...
