Question
A 1.0 kg ball is bounced high in the air. What is its total kinetic energy when it reaches its highest point?
Answers
GPT 3.5
At the highest point of the ball's trajectory, its velocity is zero (since it momentarily stops before falling back down). Therefore, the ball's total kinetic energy at the highest point is also zero, as kinetic energy is given by the equation:
KE = 1/2 * m * v^2
where m is the mass of the ball and v is its velocity. Since v is zero at the highest point, the kinetic energy is also zero.
KE = 1/2 * m * v^2
where m is the mass of the ball and v is its velocity. Since v is zero at the highest point, the kinetic energy is also zero.
