Question

if t= 0.8sec,g=10m, if the stone is thrown downwards find the speed, average speed and height



plz fast its my homework

Answer 1

v = u + gt
v = 0 + 10 * 0.8
v = 8 m/s

h = ut + 1/2 gt ^ 2
h = 0 + 1/2* 10 * ( 0.8 ) *2
h = 3.2 m

average speed = total distance / total time
= 3.2 / 0.8
= 4m/ s

Answer 2

hi free h k abhi tu......
