Question

What’s the velocity of the rocket? Use V=square root of 2KE/M A rocket with a mass of 10,000 kilograms is propelled upward with 8,000,000 joules of kinetic energy. The velocity of the rocket is ______meters/second.

Answer 1

v = sqrt(2K/m)

v = sqrt(2 * 8 * 10^6 / (10^4))

v = 40 m/s

Velocity of rocket is 40 m/s
