The Cosmo Clock 21 Ferris wheel in Yokohama, Japan, has a diameter of 100 m. Its name comes from its 60 arms, each of which can

function as a second hand (so that it makes one revolution every 60.0 s).
(a) Find the speed of the passengers when the Ferris wheel is rotating at this rate.
(b) A passenger weighs 882 N at the weight-guessing booth on the ground. What is his apparent weight at the highest and at the lowest point on the Ferris wheel?
(c) What would be the time for one revolution if the passenger’s apparent weight at the highest point were zero?
(d) What then would be the passenger’s apparent weight at the lowest point?

Answer:

Explanation:

a ) speed of passenger = circumference / time

= 2π R / Time

= 2 x 3.14 x 50 / 60

= 5.23 m /s

b )

centrifugal force = m v² /R

= (882 /9.8 ) x 5.23² / 50

= 77.47 N

Apparent weight at the highest point

real weight  - centrifugal force

= 882 - 77.47

= 804.53 N

Apparent weight at the lowest point

real weight  + centrifugal force

= 882 +77.47

= 959.47 N

c )  if the passenger’s apparent weight at the highest point were zero

centrifugal force = weight

mv² /R = mg

v² = gR

= 9.8 X 50

v = 22.13 m /s

d )

apparent weight

mg - mv² / R

= 882 - (882 / 9.8 )x 22.13²/50

= 882 +  882

= 1764 N  

=

A pitcher throws a 150g baseball so that it crosses home plate with a speed of 40 m/s. The ball hit straight back towards the pi
Fed [463]

Momentum = (mass) x (velocity)

On the way to the plate, the momentum of the ball was

(0.15 kg) x (40 m/s this way <==) = 6 kg-m/s this way <==

After the hit, the momentum of the ball was

(0.15 kg) x (45 m/s that way ==>) = 6.75 kg-m/s that way ==>

The CHANGE in momentum was 12.75 kg-m/s that way ==>

That's the momentum that the bat gave it.

Change in momentum = Impulse

Impulse = (force) x (length of time the force lasts)

12.75 kg-m/s = (force) x (0.002 second)

Force = (12.75 kg-m/s) / (0.002 second)

<em>Force = 6,375 Newtons, that way ==></em>
