Question

How long would it take for a ball dropped from the top of a 484-foot building to hit the ground?

Answer 1

Answer:

First, convert the ft to standard units of meters.

1 foot = 0.3048 meters

Therefore,

484 ft = 147.5232 meters

Then, we will use the laws of motion to calculate the time:

x = 0.5 at^2

where:

x is the displacement

a is the gravity (9.8 m/sec^2)

t is the time taken

Substitute in the equation with the givens to calculate the time as follows:

147.5232 = (0.5 x 9.8) t^2

t^2 = 147.5232 / (0.5 x 9.8)

t^2 = 30.11 seconds

t = 5.49

HOPE THIS HELPED!!!!!!!XDD
