A boy jumps from rest, straight down from the top of a cliff. He falls halfway down to the water below in 0.883 s. How much time passes during his entire trip from the top down to the water

1.25 s

Explanation:

We are given that

Initial velocity of boy=u=0

Time=0.883 s

Let x be the total distance covered by boy in entire trip.

s=

We know that

Where

Substitute the values

m

Again using the above formula

Hence, 1.25 s passes during his entire tripe from the top down to the water.

the answer is a 3.8cm

explanation:

a=d/t

a="triangle"v/t

explanation:

a = acceleration
