Answer #1

Given acceleration due to gravity = a= 9.8m/s2

distance (maximum height) = 0.390m

Final velocity= V1= 0

Inital velocity = V0= ?

Using the equation V12=V02+2* a* s

0= V02 + 2*(-9.8 m/s2) * (0.390 m)

V02 = 7.644 m2/s2

V0= 2.765 m/s

Hence the initial velocity is 2.765 m/s as it leaves the ground.
