Question: A chair of mass 11.5kg is sitting on the horizontal floor; the floor is not frictionless. You push on the chair with a force F = 40.0N that is directed at an angle of 34.0 degree below the horizontal and the chair slides along the floor.
Part A: Use Newton's laws to calculate the normal force that the floor exerts on the chair.
I need help to determine the normal force that the floor exerts on the chair.
A rocket of mass 4.5x105kg is in flight. Its thrust is directed at an angle of 49.0degrees above the horizontal and has a magnitude of6.30 x 106 N. Find the magnitude and direction of the rockets acceleration. Give thedirection as an angle above t..
