During the shot put competition at a track and field meet, a shot putter transfers 245J of energy to a 7200g steel ball he is throwing. What is the velocity of the ball?

1/2 mass*velocity^2=245

mass=7.2kg

To calculate the velocity of the ball, we need to use the equation that relates kinetic energy (K) and the mass (m) and velocity (v) of an object:

K = (1/2)mv^2

First, we need to convert the mass from grams to kilograms:

m = 7200g = 7.2kg

Now we can rearrange the equation to solve for velocity:

v = √(2K / m)

To find the velocity, we need to calculate the kinetic energy (K). The question tells us that 245J of energy is transferred to the ball.

K = 245J

Now, we can substitute the values into the equation:

v = √(2 * 245J / 7.2kg)

Calculating this, we get:

v ≈ 9.98 m/s

Therefore, the velocity of the ball is approximately 9.98 m/s.
