A 5kg baseball and a 10kg softball are thrown at 10 m/s. Which ball has more kinetic energy?
k.e. is proportional to the mass of an object and the square of its velocity
the balls have the same velocity but one has twice the mass
u didn't answer the question which has more kinetic energy
yes, he did.
twice the mass, so twice the KE
(2m)v^2 = 2*mv^2
To determine which ball has more kinetic energy, we need to use the formula for kinetic energy:
Kinetic Energy = (1/2) * mass * velocity^2
Let's calculate the kinetic energy for each ball.
For the 5kg baseball:
Kinetic Energy = (1/2) * 5kg * (10 m/s)^2
= 0.5 * 5kg * 100 m^2/s^2
= 250 Joules
For the 10kg softball:
Kinetic Energy = (1/2) * 10kg * (10 m/s)^2
= 0.5 * 10kg * 100 m^2/s^2
= 500 Joules
Therefore, the 10kg softball has more kinetic energy than the 5kg baseball.
