Question

A ball is thrown vertically upward with a velocity of 25 m per second find the time taken to reach the maximum position and the height g is equal to 10 m per second square

Answer 1

u=25m/s

g= -10 (going up)

we know,

v^2 =u^2 + 2 as

v=0

:.

0 = 625-20

20s=625

s = 31.25

we know.

v =u+at

o= 25-10t

10t=25

t = 2.5
