A soccer ball is traveling at a velocity of 50 m/s. The kinetic energy of the ball is 500J. What is the mass of the soccer ball?

0.1 kg
0.2kg
0.4kg
0.5kg

Respuesta :

Answer:

0.4 Kgs.

Explanation:

A soccer ball is travelling at a velocity of 50 m/s.

The kinetic energy of the ball is 500 J.

The mass of the soccer ball is 0.4 kgs.

This answer is derived from the formula K=1/2 MV^2.

So velocity and kinetic energy are given from that mass of the ball is calculated.

By substituting the values 500=1/2*M*50*50 which gives M=0.4 Kgs.
