Question

a stone dropped from the top of a tower 98 M high calculate the time and the velocity with which it strike the ground

Answer 1

gravity is taken to be 10m/s or 9.8m/s??

Answer 2

Answer:

98 m/s

Explanation:

t = a/s

t = 9.8/98

t = 98/98 X 10

t = 10 s

Using 1st equation of motion,

v = u + at

v = 0 + 9.8X10

v = 98m/s
