Question

stone is dropped from a height h it travels a distance of 3 in last second of its journey to the ground find time of fall to ground

Answer 1

Answer:

Time Taken: 2 seconds

Explanation:

In the last second v = 0

u = ?

g = 9.8 m/s^2

t = 1 second

v = u + at

0 = u + 9.8 * 1u

= 9.8 m/s

When it is dropped from height h,

its u = 0

v = 9.8 m/s

g = 9.8

t = ?

v = u + at

9.8 = 9.8 *t

t = 1 second

So , total time taken = 2 seconds.
