an electron moving with a speed of 5.9x10 m/s in the positive direction experiences zero magnetic force. when it moves in
the positive y direction, it experiences a force of 3.9x10-13 n that points in the positive z direction

When the velocity of an object is doubled, by what factor is its momentum changed? by what factor is its kinetic energy changed? a) the momentum is zero. b) the momentum is not zero. c) difficult to say.

Asher cycles 12 miles in 16 hours. what is his speed?

A1,700kg car is being used to give a 1,400kg car a push start by exerting a force of 140n the impulse on the smaller car during the 30.0s of contact is +670kg*m/s. what is the impulse of the smaller car on the larger car? -814 kg*m/s 0kg *m/s -670kg*m/s -550kg*m/s
