A person springs off a 12-foot high diving board with an initial velocity of 10 feet per second. How many seconds does it take the person to hit the water?

1.2 seconds

Step-by-step explanation:

The height of the diving board above water is 12 feet.

The person dives with an initial velocity of 10 feet per second.

The time taken is gotten by dividing the height jumped by the velocity at which the person dived.

That is:

t = d / s

where d = height jumped = 12 ft

s = velocity = 10 ft/s

Therefore:

t = 12 / 10 = 1.2 seconds

It took the person 1.2 seconds to hit the water.
