If the kinetic theory of a ball moving at a velocity of 10m/s is 50kj . What is the mass of the ball .
We can use the formula for kinetic energy:
KE = 1/2 mv^2
where KE is the kinetic energy, m is the mass of the ball, and v is the velocity.
Substituting the given values:
50kJ = 1/2 m (10 m/s)^2
Simplifying:
50,000 J = 1/2 m (100 m^2/s^2)
Multiplying both sides by 2:
100,000 J = m (100 m^2/s^2)
Dividing both sides by 100 m^2/s^2:
m = 1000 kg
Therefore, the mass of the ball is 1000 kg.
