Question

A diver runs horizontally off the end of a 4 m high diving board at 6 m/s.

a.) How long does it take for the diver to hit the water? s

b.) How far horizontally does the diver end up from the board? m

c.) What is the size of the horizontal (x) component of the divers velocity just before he hits the water? m/s

d.) What is the size of the vertical (y) component of the divers velocity just before he hits the water? m/s

e.) What is the speed of the diver just before he hits the water? m/s

f.) If the diver instead horizontally ran off the end at 12 m/s, which of the answers for a-e would change? Select all that apply to get credit. (Hint: you should not have to recompute anything to answer this.) part a part b part c part d part e

Explanation / Answer

ANSWER TO f:

part a wud not change as this does not involve horizontal distance term in its solution equtaion

i,e

yf = yi + Voyt + 0.5 ay t^2

---------------------------------

part B wud change as range = horizontal disance = Voy t

Rnet = R + Ro ( horizontal distance)

---------------------------

part C wud change as Vx = Vox + Vox

-----------------------------

part D wud not change as there is not Horizontal distance term

--------------

part E: part E wud change as

V = Vox^2 + Voy^2

at the emd means Vox = sum of both speeds

so

part B, part C and part E wud change
