Question

If a ball dropped from a tower reaches the ground after 3.5 seconds, what is the height of the tower?

Given: g = –9.8 meters/second2

Answer 1

You know the kinematic equation
\[x = x_{0} + vt + \frac{1}{2}at^{2}\]
right?
We can plug in the numbers:
\[x = 0 + (0)(3.5) + \frac{1}{2}(9.8)(3.5)^{2}\]
