Answer 2

Answer:

here'sthe answer

Explanation:

total time taken will be 3 + root 2 sec

u=0

t=5

g=10 (approx)

h=1/2×g×t

1/2×10×5

=25

total distance is 25

it is stopped after 3 sec

distance travelled =

h=1/2×10×3

=15

distance left

=25-15=10

now when it is released

u=0

g=10

h=10

h=1/2gt^2

h=1/2×10×t^2

t^2=10×2/10

t^2=2

t=root 2

total time=3+root2
