Answer:

here u=20 g=10

first of all hiii! here g=acceleration h=height here acceleration is acting down while object is moving up so acceleration is negative

we need some formulas to solve this :

1)u/a=t

2)h=ut+1/2×g×t^2

let's do math:

1)u/a=t

20/-10=-2sec since time is scalar -t is imprestionles so -t=t

2)h=ut+1/2×a×t^2

h=20×2+0.5×-10×2^2

h=40+-5×4

h=40-20

h=20m

hi your answer is 20m
