Answer:
1.55m
Step-by-step explanation:
The formula for calculating the maximum height is expressed as;
H = u²/2g
u is the initial velocity
g is the acceleration due to gravity
Substitute
H = 1²/2(9.8)
H = 1/19.6
H = 0.051m
Since it is launched form a height of 1.5m, the height above the ground will be 1.5+0.051 = 1.55m
