Question

if time taken by a body to reach at maximum height is 10 sec. how can we find speed at time of projection from ground using above conext? g=10m/s2

plz answer to this question please help me ​

Answer 1

Answer:

100mps

Explanation:

as given max height attained in 10 sec.

at max height final velocity will be 0.

using v = u + gt

here g = -10 because body is moving against gravity.

so, 0 = u - 100

u = 100mps
