In a box, four boxes act on an object and have the following directions and magnitudes; A = 30.4 N East, B = 55.4 N North, C = 98.7 N West, and D = 77.1 N South East.

  1. What is the magnitude of the net force (in N) on the object?

  1. What is direction of the force? (Clockwise from the positive y axis).

A crate with a mass of 8.25 kg starts from rest at the top of a 29.7 degrees incline and slides 4.0 m down the incline and takes about 2.4 seconds.

  1. What is the magnitude of the acceleration on the object in a frictionless scenario?
  2. What is the magnitude of the acceleration on the object in a scenario with friction?
  3. What would be the frictional force acting on the crate?
  4. What is direction of the force? (Clockwise from the positive y axis).

Two forces F1 and F2 act on an object. Each force is specified as an ordered pair: its magnitude in Newtons and an angle measured in degrees counter-clockwise from the positive x-axis. Let F1 = (27.0 N, ∠115° )and F2 = (83.0 N, ∠240° ). Calculate the magnitude the vector F1 - F2. Include three significant figures in your answer. (If the last digit is a zero, Canvas will not display it but that's OK.) Please HELP!
