Please answer the question attached. Thanks.

Answer 1

Answer:

SOLUTION

h = vit x 1/2 gt^2

WE HAVE gravity (acceleration due to gravity) = 10m/sec

vf = 0

vi = 20m/sec^2

t. = 2 sec

PUT THE VALUES IN EQUATION

h = 20 × 2 + 1/2 × 10 (2)^2

h = 40 + 1/2 × 10 × 4

h = 40 + 1/2 × 40

h = 40 + 40/2

h = 40 + 20

h = 60m

60m is the height through which green ball is gone through!!
