Two astronauts push on a satellite. One pushes in the positive x-direction with a force of 42N, and the other pushes in the positive y-direction. If the net force is at an angle of 15° above the positive x axis, what is the magnitude of the second astronaut’s force? Write the known and unknown from the problem, the formula, then solve.

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
