A space probe is traveling in outer space with a momentum that has a magnitude of 3.04 x 107 kg·m/s. A retrorocket is fired to slow down the probe. It applies a force to the probe that has a magnitude of 1.19 x 106 N and a direction opposite to the probe's motion. It fires for a period of 8.86 s. Determine the momentum of the probe after the retrorocket ceases to fire.

A 91 kg object has a velocity whose magnitude is 45 m/s and whose direction is 264°. What is the direction of this object's momentum (in degrees)?

Olaf is standing on a sheet of ice that covers the football stadium parking lot in Buffalo, New York; there is negligible friction between his feet and the ice. A friend throws Olaf a ball of mass 0.400 kg that is traveling horizontally at 10.7 m/s . Olaf's mass is 68.4 kg. Part A: If Olaf catches the ball, with what speed vf do Olaf and the ball move afterward?Part B: If the ball hits Olaf and bounces off his chest horizontally at 7.00 m/s in the opposite direction, what is his speed vf after the collision?

An unstable nucleus of mass 1.7x10-26 kg, initially at rest at the origin of a coordinate system, disintegrates into three particles. One particle, having a mass of m1 = 1.8x10-27 kg, moves in the positive y-direction with speed v1 = 5.2x106 m/s. Another particle, of mass m2 = 8.0x10-27 kg, moves in the positive x-direction with speed v2 = 3.6x106 m/s. Find the magnitude and direction of the velocity of the third particle. (Assume that the +x-axis is to the right and the y-axis is up along the page.) magnitude          m/s direction         ° I know that the direction is 198.97, I keep getting my magnitude wrong. Help me find the magnitude

Impulse and momentum problem: A stationary 1.25-kg object is struck by a stick. The object experiences a horizontal force given by F = 1,520{N/(ms)} t - 19{N/(ms)2}t2, where t is the time in milliseconds from the instant the stick first contacts the object. What is the speed of the object just after it comes away from the stick at t = 2.11 ms? (Give answer to the nearest 0.1 m/s)
