Then solve for the normal force in terms of the weight of the box, mgand the angle of inclination, such as mg cos(?) Make it clear on your diagram how the angle is used in finding force components
A man pulls a crate with a rope. The crate slides along the floor in the horizontal direction (x direction). The man exerts a force of 50 N on the rope, and the rope is at an angle 0. Described how the force components (Fx,Fy) change as the angle increases from 0 degrees to 90 degrees and use your graph to explain your answer. Give a detailed explanation of the forces at 0= 0, 45degrees, and 90 degrees. please show a sample calculation at one angle for both components. 
The diagram below is comprised of four vectors A, B. C and D. Using addition and subtraction of vectors, describe the following:
D

If a passenger vehicle travels in a circular path at too high a speed, it can tip over. The image below shows a vehicle beginning to tip over. A group of students investigated the speed at which a passenger vehicle will begin to tip over by using a remote- control toy car. The students drove the car around circular paths of various known radii, at such a speed that it was just starting to tip for each radius. They timed the period of the cars motion and used the period to calculate the 'tipping speed' (the speed at which the toy car begins to tip over) of the car. The graph below shows the data collected by the students: Speed at which toy car begins to tip over (m s'¹') 14 12 10 8 TESTO 0 2 3 Radius (m) 5 6 7 Page 11arrow_forwardThe three diagrams below show a block of mass m being pulled or pushed at constant acceleration along a table with a force F.
