A 70 kg high jumper is attempting to clear a bar at a height of 2 meters. The coefficient of friction between his foot and the ground is 0.35. The resultant force of all of the forces just prior o take off when his foot is stillin contact with the ground is equal to 400 Newtons straight up What is the magnitude and direction of all of the forces that make up this net/result the problem (There is no drag force from any wind)? ant force in Two opposing team volleyball players both reach to block a ball at the exact same time. Player A exerts a force that is 300 Newtons directed straight at the opposing player. Player B exerts a force that is 400 Newtons directed at an angle of 10 degrees to the left of the opposing player What is the magnitude and direction of the resultant force? SoHCAHTOA Adj Hyp
