The Initial height of the tire will be 0.32 m

Explanation:

We  have the formula,

h=Vf^2/2g

h=V×f×f/2g

where Vf denotes the speed of the tire at the bottom of the swing

where g denotes the acceleration

due to the gravity

h=2.5×2.5=6.25

2×9.8 =19.8

h=6.25/19.8

h=0.32

The Initial height of the tire will be 0.32 m
