Question

a stone projected vertically up from the top of the tower with velocity of 19.6m/s aches it's foot in 6sec . find the height of the tower and the velocity with the stone reaches the ground​

Answer 1

Answer:

29.4m

Explanation:

From second equation of motion, s=ut+at

2

/2

Assume upward direction to be positive.

u=4.9 m/s, t=3 sec, a=−9.8 m/s

2

s=4.9×3−9.8×3

/2

s=−29.4 m

Height = 29.4 m
