Two air carts of mass m1 = 0.83 kg and m2 = 0.45 kg are placed on a frictionless track. Cart 1 is at rest initially, and has a spring bumper with a force constant of 690 N/m. Cart 2 has a flat metal surface for a bumper, and moves toward the bumper of the stationary cart with an initial speed v= 0.66 m/s . Assume that positive x-axis is directed toward the direction of motion of cart 2.

a)What is the speed of the two carts at the moment when their speeds are equal? Express your answer using two significant figures.

b) How much energy is stored in the spring bumper when the carts have the same speed? Express your answer using two significant figures.

c) What is the final speed of the cart 1 after the collision?Express your answer using two significant figures.

d)What is the final speed of the cart 2 after the collision?Express your answer using two significant figures

Two carts are rolling to the right along the same level track. Cart 1 (m1 = 3.81 kg) is in the rear, rolling at a speed of 6.25 m/s and catching up to cart 2, rolling at 3.07 m/s. Round final results to 3 digits. a) Cart 1 of course overtakes and collides with cart 2. Velcro pads on the carts make them stick together during the collision, after which they both continue rolling right, but at a speed of...
