- A 600 kg cart is connected to a 200 kg wagon which are travelling together. The total momentum of the cart-wagon system is 1600 kg*m/s. The wagon and cart then separate so the cart has a final velocity of 3
m/s. What is the final total momentum of the cart-wagon system?

What is the increase in density of a medium due to wave travel?

An athlete swings a ball, connected to the end of a chain, in a horizontal circle. the athlete is able to rotate the ball at the rate of 8.13 rev/s when the length of the chain is 0.600 m. when he increases the length to 0.900 m, he is able to rotate the ball only 6.04 rev/s. (a) which rate of rotation gives the greater speed for the ball? 6.04 rev/s 8.13 rev/s (b) what is the centripetal acceleration of the ball at 8.13 rev/s? m/s2 (c) what is the centripetal acceleration at 6.04 rev/s? m/s2
