I’ll give brainliest A 24 kg go-cart moves at a speed of 10.0 m/s. The engine exerts 50.0 N force to
accelerate the cart over a distance of 30.0 m.
(a)
What amount of work did the engine do on the cart?
(b)
What is the cart's final kinetic energy?
(c)
What will be the cart's final speed?

Suppose you use a machine that gives you a mechanical advantage of 2 to achieve an output force of 30newtons what must the input force be

Air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. initially, air is at 400 kpa and 17°c. the paddle wheel is now turned by an external electric motor until 75 kj/kg of work has been transferred to air. during this process, heat is transferred to maintain a constant air temperature while allowing the gas volume to triple. calculate the required amount of heat transfer in kj/kg.
