A student with a mass of 45 kg stands on a bathroom scale in an elevator. What can you say about the motion of the elevator at the moment that the bathroom scale reads 360 N? Use a force diagram and be as precise as you can when answering. Find the exact acceleration.

The fuel burns exerting a time-varying force on the small 2.00 kg rocket model during its vertical launch. This force obeys the equation F= A + Bt2. Measurements show that at t=0, the force is 25.0 N, and at the end of the first 2.00 s, it is 45.0 N. Assume that air resistance is negligible.   What are the forces acting on the rocket?          2. Draw its free-body diagram.   Please encode your answers and don't handwrite it

A brown box slides horizontally at a constant velocity on a frictionless surface. Which free body diagram represents this situation? Explain your reasoning. A N mg push N mg B

Please write the solution clearly

I ONLY NEED THE FREE BODY DIAGRAM. NO NEED FOR SOLUTION OR ANSWER

An object is moving to the right in a straight line. The net force acting on the object is also directed to the right, but the magnitude of the force is decreasing with time. The object will... A. continue to move to the right with a constant speed stop and then begin moving to the left. continue to move to the right, with its speed decreasing with time D. continue to move to the right, with its speed increasing with time.

Q4. An 80 kg dog is lying on the floor at rest. The coefficient of kinetic friction between the dog and the floor is μ = 0.2. Ignore static friction. If the dog is pulled by a person with a 200 N force as shown, determine the speed of the dog when t = 3 s. [Do NOT use the equations of motion i.e. Σ F = ma, directly; otherwise your solution to this qustion will receive a zero]. 60⁰ P-200 N

O d. 4.94 An object of mass 5kg is sliding with a constant velocity of 10m/s on a frcitionless horizontal table. The force needed to keep the object moving with the same velocity is. Select one: a. 8 N O b. 2 N О с. ОN O d. 4 N A 105 N traffic light is supported by three cables (T, T2 and T3), of which T, and T2 are making angles 0, = 72° and 02 = 23° as shown in Figure. %3D Here T3 105 N, calculate the tensions T, and T2.

Draw a motion diagram, a force identification diagram, and a freebodydiagram. For the situation described. You’ve slammed on the brakes and your car is skidding to a stop while going down a 20° hill.
