A young girl threw a 1 Kg stone vertically upward into the air. Her hand moved through a distance of 0.5 m before the stone left her hand. If the stone reaches a maximum height of 20 m above her hand’s starting point, what force did she apply to the stone? Assume the force was constant and ignore air resistance.

    article Is uncharged and is thrown vertically upward from 1 with a speed of 25.0 m/s. As a result, it attains a height h. The particle is then given a positive charge and reaches the same maximum height h when thrown verti- ly upward with a speed of 30.0 m/s. The electric potential at height h exceeds the electric potential at ground level. Finally he particle is given a negative charge-q. Ignoring air resistance determine the speed with which the...
