SUMMARY
The momentum of a 0.12 kg ball of dough thrown straight up with an initial speed of 11 m/s reaches zero at its maximum height due to the complete conversion of kinetic energy into potential energy. The acceleration of gravity is 9.8 m/s², which affects the ball's upward motion. To calculate momentum at any point, the formula p = mv must be used, where p is momentum, m is mass, and v is velocity. At maximum height, the velocity is zero, resulting in a momentum of 0 kg m/s.
