Question

If a ball is dropped from a bridge that is 30 meters high, how long will it take until the ball hits the ground below the bridge? Round your answer to one decimal place.

Answer 1

The ball will take approximately 2.2 seconds to hit the ground.

Step-by-step explanation:

To find the time it takes for the ball to hit the ground, we can use the equation for free fall:

t = sqrt(2h/g)

where t is the time, h is the height, and g is the acceleration due to gravity.

Plugging in the values, we get:

t = sqrt(2 * 30 / 9.8) = 2.2 seconds

Therefore, it will take approximately 2.2 seconds for the ball to hit the ground.
