A lab cart has a mass of 50 grams and an initial velocity of just 0.2 m/s, right. It is pushed to the right by a force. The cart covers 7.25 m and gains a velocity of 0.7 m/s, to the right. If the acceleration of the cart was 0.1 m/s/s, to the right, how long did it accelerate? For credit, show work in detail.

Two people each hold the end of a rope and create waves by moving their arms up and down. this wave is best classified as a transverse wave because a) both the rope particles and the wave are moving in the same direction. b) the wave is moving up and down as the particles of the rope move horizontally. c) the wave is moving horizontally as the particles of the rope move up and down. eliminate d) the wave is moving in a parallel direction with the motion of the person's arms.
