Question

The potential energy of a 25 kg bicycle resting at the top of a 3 m high hill is
J. (gravity= 9.8 m/s2)

Answer 1

Respuesta:

U = 68.1 Kj

Explicación paso a paso:

Potential energy formula (U) :

U = mgh

U = (25kg)*(9.8 m/s^2)*(3m)

U = (22,700 N)*(3m)

U = 68,100 J

68, 100 J a Kj =  (68,100)*(0.001)  

U = 68.1 Kj
