A 2 kg ball is thrown with a velocity of 10 m/s. If the energy is delivered by a machine in 0.5 s, what is the machine's power output?
To find the power output of the machine, we first need to calculate the kinetic energy imparted to the ball and then use the power formula.
Calculate the kinetic energy of the ball
The formula for kinetic energy is:
Where:
is the mass of the ball,
is the velocity of the ball.
Substitute the values:
