1.
In Activity 1, which way did the blue marble travel when the cup was removed? If How does the velocity of the bobber when spun with a mass of 14 washers in the cylinder compare with the velocity of the bobber when spun with a mass of 8 washers in the cylinder? The marble traveled in a straight path off the table after I removed the plastic cup. The more mass that was added the quicker the bobber spun. 2.
Describe the relationship between the mass of the cylinder with the washers and the velocity of the bobber. Every time I added a washer, it took less time for the bobber to get 30 rotations. 3.
What do you notice about the relationship between the centripetal force and the weight of the cylinder with washers? Explain the reason for this relationship. Centripetal force increased every time the washer weight increased. 4.
How will centripetal force be affected if you double the velocity at which you spin the sphere? I believe the centripetal force would double as well. 5.
What would you expect to happen to the velocity of the bobber if the mass of the washers in the cylinder remained the same and the radius was doubled? I would predict the velocity of the bobber to decrease.

Problem 1: Gnome Ride - This from a Previous Exam
I.
A Gnome of given mass M goes on the Gnome Ride as follows: He stands on a horizontal
platform that is connected to a large piston so that the platform is driven vertically with a position
as a function of time according to the following equation:
y(t) = C cos(wt)
Here w is a constant given angular frequency, C is a given constant (with appropriate physical
units) and y represents the vertical position, positive upward as indicated.
Part (a) - What is the velocity of the Gnome at time t = 0? Explain your work. Present your
answer in terms of the given parameters
Part (b) – What is the net force on the Gnome at time t = 0? Explain your work. Present your
answer in terms of the given parameters
Part (c) – What is the Normal Force on the Gnome at time t = 0? Explain your work. Present
your answer in terms of the given parameters

Answer TWO questions from this section
ENG2012-N
The moment of inertia of a helicopter's rotor is 320kg. m². The rotor starts from rest
and at t = 0, the pilot begins by advancing the throttle so that the torque exerted on
the rotor by the engine (in N.m) is modelled by as a function of time (in seconds) by
T = 250t.
a) How long does it take the rotor to turn ten revolutions?
b) What is the rotor's angular velocity (in RPM) when it has turned ten
revolutions?
