A wrecking ball has a mass of 315 kg. If it is moving at a speed of 5.12 m/s, what is its kinetic energy? *Please I need a clear explanation so i can complete the rest on my own*

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.

the moving of the box is a result of centripetal force. think of that  as a car or a truck in this case creates a turn, the force of friction performing upon the turned wheels of the car runs centripetal force obligatory for circular motion for the things inside it.
