Answer 1

See below

Step-by-step explanation:

vf = vo + at when it reaches top vf = 0 vo = 10m/s a = -9.81 m/s^2

0 = 10 + (-9.81) t

t = 1.02 seconds to reach max

time up = time down so roundtrip = 2.04 seconds

Answer 2

Here given is :-

Velocity (u) = 10m/s

Gravity (g) = 10 m/s²

Height (h) = ?

Step-by-step explanation:

v² - u² = 2gh

0² - 10² = 2 × (-10) × h

-100 = -20 h

`h = ( - 100)/( - 20) = 5m`

V = u + gt

0 = 10 - 10t

10t = 10

`t = (10)/(10) = 1 \: sec`

Total time = 2 sec
