A trapeze artist weighs 8.00 x 10^2 N. The artist momentarily held to one side of a swing by a partner so that both of the swing ropes are at an angle of 30ยบ with the vertical. In such a condition of static equilibrium, what is the horizontal force being applied by the partner?

An elevator weighing 2.00 x 10^5 N is supported by a steel cable. What is the tension in the cable when the elevator is accelerated upward at a rate of 3.00 m/s^2?

A 65.0 kg ice skater standing on frictionless ice throws a 0.15 kg snowball horizontally at a speed of 32.0 m/s. At what velocity does the skater move backward?

Two skaters, each with a mass of 50 kg, are stationary on a frictionless ice pond. One skater throws a 0.2 kg ball at 5 m/s to the other skater, who catches it. What are the velocities of the skaters when the ball is caught?

the horizontal force of the trapeze artist would be Wxcos(30) and for the swing to stay still it would have to be the equal force by the partner
