Aparticle traveling in a straight line is located at the point (1, 0, −1) and has speed 3 at time t = 0. the particle moves toward the point (3, 4, 3) with constant acceleration 2i+ 4j+ 4k. find the velocity v(t) and the position r(t) of the particle at time t.

When a 5.0kg cart undergoes a 2.2m/s increase in speed, what is the impulse of the cart

Any color picture tube and electric field exerts a net force of magnitude 1.68x 10^-13 n on an electron the rest mass of an electron is 9.11 x 10^-13 what is the electron acceleration?

Mutt and jeff are running along a path each pushing a cart loaded with rocks. if mutt's wagon has a mass two times greater than jeff's and they want to stay together, arriving at their destination at the same time, what must happen? a) jeff should slow down so mutt can catch up. b) mutt must use half as much force to push his cart. c) mutt must use twice as much force to push his cart. d) mutt and jeff will use the same force, but mutt will take bigger steps.
