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 15Ā° above the positive x axis, what is the magnitude of the second astronautās force? Write the known and unknown from the problem, the formula, then solve.
