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
