Question

A soccer ball is traveling at a velocity of 50 m/s. The kinetic energy of the ball is 500 J. What is the mass of the soccer ball? (Formula: KE = 1/2mv^2 )
0.1 kg
0.2 kg
0.4 kg
0.5 kg

Answer 1

Answer:

c. 0.4 kg

Explanation:

i guessed but when i looked i was actually right. hope this helps:)

Answer 2

A soccer ball is traveling 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.
