Answer: 61.25m
Explanation:
To solve this, the formula used will be:
h = -16t^2 + vt + h(o)
where,
Initial velocity, v = 60mph
Height, h = 5 feet
t = ?
After solving for t, we get t = 1.875 seconds. We then slot it back into the equation.
h = -16t^2 + vt + h(o)
h = -16(1.875)^2 + 60(1.875) + 5
h = -56.25 + 1112.5 + 5
h = 61.25m
