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 A. 56.00 meters B. 60.03 meters C. 62.08 meters D. 62.50 meters

Respuesta :

Answer:

B. 60.03 meters.

Step-by-step explanation:

We use the equation of motion under gravity:

h = ut - 0.5gt^2      where h = height, t = time and u = initial velocity.

h = (0)(3.5) - 0.5 * -9.8 * 3.5^2

= 60.025 m.
