1.	A stone is thrown vertically upwards with a speed of 20m/s. How high will it go before it beings to fall?
Answer» Initial velocity, u = 20 m/s Final velocity, v = 0 Acceleration due to gravity, g = -9.8 m/s² Height, h = ? Using the relation v² = u² + 2gh h = 20.4m Initial velocity, u=20m/s Final velocity, v=0 Acceleration due to gravity, g=-9.8m/s2 Height, h=? Using relation, for a freely falling body: v2 = u2 + 2gh (0)2 = (20)2 + 2 x (-9.8) x h 0-400 = -19.6 h h= 400/19.6 = 20.4 m

Answer»

Initial velocity, u = 20 m/s

Final velocity, v = 0

Acceleration due to gravity, g = -9.8 m/s²

Height, h = ?

Using the relation v² = u² + 2gh

h = 20.4m

Initial velocity, u=20m/s Final velocity, v=0 Acceleration due to gravity, g=-9.8m/s2 Height, h=? Using relation, for a freely falling body: v2 = u2 + 2gh (0)2 = (20)2 + 2 x (-9.8) x h 0-400 = -19.6 h h= 400/19.6 = 20.4 m
