Question

A ball is tgrown vertically upwards woth a speed of 14.6m/s from the top of a towre returns to the earth in 6s.find the height of the tower..

Answer 1

HEYA!!
----------

Given that ,

Initial velocity u = 14.6 m/s.

Time t = 6 sec

Final velocity V = 0

H = ?

----------------------------------------------------------------------------------------------------

Now using the second equation of motion,

$s = ut + \frac{1}{2} at {}^{2}$


-H = 14.6 × 6 + 1/2 × -9.8 × 36

= 88.8 m
