gravity slows the stone 9.8 m/s for every second of upward flight
... the stone stops at max height and begins to fall back down
time to max is ... (20 m/s) / (9.8 m/s^2)
A stone with a mass of 6kg is thrown vertically upwards from the top of the building 35m high with a starting velocity 20m/s .
Determine the time it will take the stone to reach it's maximum height.
