Question

a piece of stone is thrown up it reaches maximum height in 10 sec . what is the initial speed with which it is thrown up​

Answer 1

Answer:

0

Explanation:

because the starting will be 0

Answer 2

Answer:

given ,

time taken = 10 sec

v = 0

a = g = -10 m/s²      [ since it is a vertically projected body ]

v = u+at

0 = u -10×10

-u = -100

- gets cancelled on both sides

u = 100 m/s

Hence, the stone would have been thrown with 100 m/s speed if the stone reached the maximum height in 10 sec .
