Question
A child stands on a cart initially at rest. The cart and child together have mass of 60kg. Also on the cart are three large blocks. Blocks A has a mass of 10kg, block B has a mass of 20kg, and block C has a mass of 30kg. The child throws each block horizontally away from the cart with a speed of 12 m/s relative to cart always.

4. A child stands on a cart initially at rest. The cart and child together have mass of 60 kg. Also on the cart are three large blocks. Block A has a mass of 10 kg, block B has a mass of 20 kg, and block C has a mass of 30 kg. The child throws each block horizontally away from the cart with a speed of 12 m/s relative to the cart always. a) Determine the speed of the cart and child, relative to the ground, after each block is tossed out backwards by the child. After block C is tossed out: Then, after block B is tossed out: Then, after block A is tossed out: b) What combination would maximize the velocity? (all three at once, two then one, one then two, one at a time in a different order) Show calculations!

    4. Energy and Momentum for 15 points: A 200 gram lab cart is initially at rest on top of a 50 cm ramp, as shown. Note that the wheels are very light and the axle has no friction in it. You push the cart as it moves through a distance of 20 cm with a constant force of 10N in a direction oriented 20 degrees below horizontal. After you stop pushing on the cart, it encounters a ramp, and rolls...

    A block of mass m1 = 1.10 kg moving at v1 = 1.20 m/s undergoes a completely inelastic collision with a stationary block of mass m2 = 0.900 kg . The blocks then move, stuck together, at speed v2. After a short time, the two-block system collides inelastically with a third block, of mass m3 = 2.40 kg , which is initially at rest. The three blocks then move, stuck together, with speed v3. Assume that the blocks slide without...

    ​Two blocks, A and B, are initially held together by a string as shown in the figure; the mass of block A is of 2 kg and the mass of block B is 4 kg. The massless spring in-between the two blocks has a spring constant of k = 655 N/m and is initially compressed by 45 cm. The two blocks are initially moving together with a speed of 1 m/s. When the string is cut (i.e., when the blocks...
