Question

A football player has a mass of 110 kg. He is running at a speed of 16 mph, equivalent to 7.2 m/s. What is his kinetic energy when he tackles the opposing team's quarterback? KE = 1/2mv^2
GPT 3.5
The kinetic energy (KE) of the football player can be calculated using the formula:

KE = (1/2) * m * v^2

where
m = mass of the football player (110 kg)
v = velocity of the football player (7.2 m/s)

Plugging in the given values:

KE = (1/2) * 110 kg * (7.2 m/s)^2

Simplifying:

KE = (1/2) * 110 kg * 51.84 m^2/s^2

KE ≈ 2839.2 Joules

Therefore, the football player's kinetic energy when he tackles the opposing team's quarterback is approximately 2839.2 Joules.
