A box with a mass of 3.50 kg is initially at rest on a horizontal frictionless surface. You then pull on a string attached to the box, exerting a constant force F at an angle of 45° above the horizontal. This pull causes the box to travel 4.00 m horizontally in 2.00 s. Use g = 9.80 m/s². (a) First, find the box's acceleration by treating this as a one-dimensional constant-acceleration problem. m/s² (b) Find the magnitude of the force F. (c) Find the magnitude of the normal force acting on the box.
