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: )
0.1 kg
0.2 kg
0.4 kg
0.5 kg

Answer 1

Answer : The mass of the soccer ball is, 0.4 Kg

Explanation : Given,

Kinetic energy  of the ball = 500 J

Velocity of the ball = 50 m/s

Formula used :

$K.E=\frac{1}{2}\times m\times v^2$

where,

K.E = kinetic energy  of the ball

m = mass of the soccer ball

v = velocity of the ball

Now put all the given values in this formula, we get  mass of the soccer ball.

$500J=\frac{1}{2}\times m\times (50m/s)^2$

$m=0.4Kg$

Therefore, the mass of the soccer ball is, 0.4 Kg
