You drop a 0.625 kg basketball from waist height. The basketball is movingdownwards at 4.5 m/s just before hitting the ground and it is movingupwards at 3.8 m/s just after bouncing back from the ground. The bouncelasts 38 milliseconds. That is, the ball is in contact with the ground for 38milliseconds.

Given information:The mass of the basketball is m = 0.625 kgThe velocity of the basketball just…

A fast train bump into a slow train going the same direction, and they get coupled together. The fast train was initially going 6.93 meters per second and the slow train 3.1 meters per second. What is the final speed (in meters per second) once the two are coupled?
Yesterday you saw in the news that the Giant Asian Murder Hornet has migrated to North America. You didn't think much about it until today when one of those suckers crashed at high speed into the screen door at the back of your house (splat!). The thing hit the door so hard that the door swung shut!We will assume that GAMH had a mass of m = 0.069 kg and was moving with an amazing velocity of v = 9.2 meters/second. The GAMH splatted a distance d = 0.65 meters from the hinge. The door itself can be treated as a rod of mass M = 0.955 kg with a length of L = 1.00 meters rotating about its end.Determine all the following:Write the FORMULA for the moment of inertia of the door without the hornet: I = kg m2Write the FORMULA for the moment of inertia of the door with the hornet: I = kg m2Determine the angular momentum of the hornet before it collides with the door Lhornet = kg m2/sDetermine the angular velocity of the hornet-stained door after the collision ?2 =…

The following equation describes the motion of a rocket that is expelling a total mass M of fuel at a rate α = -dm/dt: dv/dt = uα/(M-αt), where u is the speed the fuel is ejected, v is the velocity of the rocket in the x-direction, and t is time. Assume the velocity at t = 0 is v(0) = 0, and that M, u, and α are constants. A particular rocket burns fuel at a rate of 5.7 kg/sec with a propellant speed of 5.99 m/sec. The total mass of fuel is 133.1 kg. What is the speed (m/s) of the rocket at t = 2.8 sec? At what time (s) will the rocket run out of fuel and no longer be accelerating? Assume negligible rocket body mass.
