A 10.0-kg test rocket is fired vertically. When the engine stops firing, the rocket’s kinetic energy is 1960 J. After the fuel is burned, to what additional height will the rocket rise?

Answer:

20m

Explanation:

So the formula for PE(Potential Energy) = Mass x Acceleration x Height

So we are given the following

PE = 1960

Mass = 10Kg

Acceleration = 9.8m/s^2 (The reason we have an acceleration is due to gravity)

Height = ?

So to calculate height we will use the same formula

1960 = 10 x 9.8 x h

1960 = 98 x h

1960 = 98h

we divide 98 on both sides

H = 20m
