Question

A 19 kg ball has an initial velocity of 10 m/s. How much energy will be transformed into gravitational force?

Answer 1

E = 950 J

Step-by-step explanation:

The total amount of energy that can be transformed into gravitational energy will be equal to the kinetic energy of the ball at initial state:

`E = K.E = (1)/(2) mv^2`

where, E = Energy = ?

m = mass of the ball = 19 kg

v = initial speed of the ball = 10 m/s

Therefore,

`E = (1)/(2) (19\ kg)(10\ m/s)^2`

E = 950 J
