Answer 1

Explanation:

direct formula to find maximum height=2u/g

u=40m/s

g=10m/s^2

2×40/10=8metre

Answer 2

I will try just two minutes.

u=40 meter per second. v=0. v square - u square = 2gs . first we know that the stone is thrown in upward so we take g = -10 now put the values 0 ka square - 40 ka square = 2 × - 10 × S. -160 = -20s. s= -160÷-20 = 8m. total height = 8 + 8 = 16 m . hope it's help you mark me as brainliest please.
