A stone of mass 160 g160\text{ g}160 g is launched from the ground at an initial velocity of 18 m/s18\text{ m/s}18 m/s vertically upwards. It decelerates until it is at rest momentarily at a height hhh above the ground.
Define deceleration.
The acceleration of free fall is 9.8 m/s29.8\text{ m/s}^29.8 m/s2. Show that the time taken for the stone to reach height hhh is 1.8 s1.8\text{ s}1.8 s. Ignore the effect of air resistance.
Calculate hhh. Ignore the effect of air resistance.
The stone is dropped from the top of a tall cliff. Describe and explain the motion of the stone as it falls. Consider the effect of air resistance in your answer.
