Spiderman has a mass of 80 kg. He knows his webbing will break if it is exposed to a 200 N force. What is the maximum height he can swing off of? You can assume aerodynamic forces prevent Spiderman from travelling greater than 30 m/s.

Ineed extreme for task 2. my student number is 571721. many to whoever solves this correctly, im in debt to you.

What is relative velocity? in which condition is relative velocity known by adding the velocity of the first body and that of the second body

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
