In the figure below, the mass the body is 10.0 kg, and F1=30.0 N, F2 = 20.0 N and F3 = 50.0 N. The angles θ1 = 32o and θ2 = 41o. Write Newton’s Laws in terms of F1, F2, F3, and along the x and y axes by first calculating the components of each force along the x and y axes. Calculate the accelerations in the x and y directions. Calculate the magnitude and direction of the net acceleration of mass m. If the mass was initially at rest, which direction will it start moving? What is the direction of the net force? If the mass is initially moving along the positive y-axis, what is the effect of the acceleration on its speed and direction?

Question

In the figure below, the mass the body is 10.0 kg, and F1=30.0 N, F2 = 20.0 N and F3 = 50.0 N. The angles θ1 = 32o and θ2 = 41o.

 

  1. Write Newton’s Laws in terms of F1, F2, F3, and along the x and y axes by first calculating the components of each force along the x and y axes.
  2. Calculate the accelerations in the x and y directions.
  3. Calculate the magnitude and direction of the net acceleration of mass m.
  4. If the mass was initially at rest, which direction will it start moving? What is the direction of the net force?
  5. If the mass is initially moving along the positive y-axis, what is the effect of the acceleration on its speed and direction?
