A space vehicle is traveling at 4100 km/h relative to Earth when the exhausted rocket motor is disengaged and sent backward with a speed of 76 km/h relative to the command module. The mass of the motor is four times the mass of the module. What is the spe...

In February 1955, a paratrooper fell 370 m from an airplane without being able to open his chute but happened to land in snow, suffering only minor injuries. Assume that his speed at impact was 62 m/s (terminal speed), that his mass (including gear) was 7...

an overhead view of the path taken by a 0.162 kg cue ball as it bounces from a rail of a pool table. The ball's initial speed is 1.11 m/s, and the angle è1 is 64.7°. The bounce reverses the y component of the ball's velocity but does not alter the x compo...

the question gives a F(x), the force acting on a car vs t(s). It asks you to find in unit-vector notation p (momentum) I know that p is the area under the curve, but how would you write this in unit vector notation?
