A car weighing 5,500kg travels at a speed of 55km/h up a hill. What is its mechanical energy? Hint: In order to answer this question, you need to find the PE and KE first.

Respuesta :

Explanation:

mass=5500kg

speed=55km/hr

height =15m

M.E=K.E+P.E

K.E=1/2mv×v

K.E=0.5×5500×15.278

K.E=641897.53J

P.E=mgh

P.E=5500×9.81×15

P.E=809325J

M.E=641897.53J+809325J

M.E=1451222.53J
