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

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.

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...

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 billiard ball of mass = 300.0 g moving with an initial speed of 1.80 m/s strikes a second ball of mass mg 400.0 g initially at rest, As a result of the collision, the first ball is deflected off at an angle of 25.0 0 with a speed of 1.00 m/s. Do not assume this is a perfect collision, (a) Taking the x-axis to be the original direction of the motion of ball A, write down the equations of...
