The graph above shows the position x as a function of time for an 3.0 kg object in motion. At 2.0s the object changes its velocity. What is the change in momentum of the object?

A 100 g cart initially moving at +0.5 m/s collides elastically from a stationary 180 g cart. Calculate the change in the momentum of the 100 g cart.

A pitcher throws a baseball of mass m = 0.150m=0.150 kg with a velocity of 43.7 m/s. The momentum of the baseball is  a numerical answer below. Accepted formats are numbers or "e" based scientific notation e.g. 0.23, -2, 1e6, 5.23e-8   .....  k x xg /s

Dr. Knotts's kids are chasing each other through the yard. Arlo is in the lead and Greyson is chasing him from behind. Arlo has a mass of 13.1 kg and is running at 1.06 m S After they run into each other, Greyson has a velocity of 1.14 19.6 kg and is running in the same direction at 1.44 How fast is Arlo moving just after they collide? VArlo m S What is the total kinetic energy of the system before the collision? KEinitial J = What is the total kinetic energy of the system after the collision? KEfinal J = Is this collision considered eleastic, inelastic, or both? O Inelastic Both Elastic m S m S in the same direction he was already moving. I I Greyson has a mass of

A car (mass = 1110 kg) is traveling at 31.2 m/s when it collides head-on with a sport utility vehicle (mass=2900 kg) traveling in the opposite direction. In the collision, the two vehicles come to a halt. At what speed was the sport utility vehicle traveling? vo, car VO, SUV Before collision After collision
