Now let's consider forces and Newton's Laws. Discuss the following. A box with a mass of 100 kg is on a frozen lake (no friction). A force of 200 N to the left, and another force of 200 N to the right act on the box. Describe the motion of the box. Also, if a car with a constant speed is turning a level corner, is there a net force acting on the car?

Forces and Newton's LAWS WU PHYS 1107 - General Physics I ) An 9.0 kg mass (M) is placed on a horizontal surface. A massless rope runs over a frictionless massless pulley which connects the mass M to a 6.5 kg mass (m) that hangs vertically. a) What is the acceleration of the vertical mass if the horizontal surface is frictionless? b) What is the tension in the rope if the horizontal surface is frictionless? Now assume that the horizontal...

Part I - Newton's First Law Make sure the boxes that say “Force” and “Speed” are checked. a. Apply a force of 50 N right to the box. Describe the motion of the box using physics terms (i.e. velocity, acceleration, displacement). Refer to the speedometer in your answer. b. Reset the scenario (don't forget to check force, speed again). Apply a force of 50 N to the right for about 5 seconds then reduce the applied force to zero (the...

In a garden nursery a large box of flower seeds (mass 18kg) is pushed 1.6m along a horizontal floor by a woman who is exerting a force of 1.5E2 N at 22o below the horizontal. The coefficient of kinetic friction between the box and the floor is 0.55. a) Use Newton's laws of motion to determine the magnitudes of the normal force and friction force on the box. b) use conservation of energy to determine the final speed of the...
