I need help on this as quickly as possible. It is about Newton's Third Law as well as the law of conservation of momentum. I have everything else down but mainly need help with question #3. I believe that the answer for question number three is something on the lines of Newton's Third Law and how forces act in an equal and opposite manner but am not sure. Thanks

Awheelhas a radius of 4.8 m. howfar (path length) does a point on the circumference travel if thewheel is rotated through angles of 30°, 30 rad, and 30 rev,respectively?

The car hoist allows the car to be driven onto the platform, after which the rear wheels are raised. if the loading from both rear wheels is 1380 lb, determine the force in the hydraulic cylinder ab. neglect the weight of the platform itself. member bcd is a right-angle bell crank pinned to the ramp at c. the force is positive if in tension, negative if in compression.

Crowbar of 5 metre is used to lift an object of 800 metre if the effort arm is 200cm calculate the force applied
