A/ Can someone help me, how can the third law of motion (Newton) help solve a problem / issue. be specific b/ how can pushing off a wall on a skateboard demonstrate the third law of Newton. If needed use gravity, friction, and air resistance.

c/ How can dropping a ball on the ground demonstrate the third law of Newton. If needed use gravity, friction, and air resistance.

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
