Answer to Question #159924 in Mechanics | Relativity for jlfgj

Question

1. A comet with a mass of 75,000 kg is moving with a velocity of 25,000 m/s. Calculate its kinetic energy.

Answer 1

Solution:

Equation of kinetic energy is

$$KE=\dfrac{mv^2}{2}$$

Given:

m = 75,000 kg

v = 25,000 $(\frac{m}{s})$

$$KE=\dfrac{(75,000kg)(25,000(\frac{m}{s}))^2}{2}$$

Answer:

The comet’s kinetic energy is $KE = 23437.5 J$
