Question

Platform diving in the Olympic Games took place at a height of 10 meters. a. What is the velocity of a diver entering the water from the platform if he steps off the platform? b.How much time does it take the diver to reach the water from the platform?

Answer 1

a)14.0m

b) 1.43s

Step-by-step explanation:

Using the equation of motion to find the velocity

S = ut+1/2gt²

10= 0+1/2(9.81)t²

10 = 4.905t²

t² = 10/4.905

t² = 2.0387

t = √2.0387

t = 1.43secs

Next is to calculate the velocity using the formula:

v = u+gt

v = 0+(9.81)(1.43)

v = 14.0m/s
