A sphere with the same mass and radius as the original cylinder, but a smaller rotational inertia, is
released from rest from the top of the ramp. K.
and K, are the sphere's and the cylinder's total
kinetic energy at the bottom of the ramp,
respectively. How do K, and K, compare, and
why?
(A) K, rotational kinetic enqey.
(B) Ks greater acceleration and therefore has
less time to gain kinetic energy.
(C) Ks = Kc , because both objects accelerate
at the same rate.
(D) Ks = Kc , because the gravitational force
does equal work on each object as it rolls
down the ramp.

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

Part f - example: finding two forces (part i) two dimensional dynamics often involves solving for two unknown quantities in two separate equations describing the total force. the block in (figure 1) has a mass m=10kg and is being pulled by a force f on a table with coefficient of static friction îľs=0.3. four forces act on it: the applied force f (directed î¸=30â above the horizontal). the force of gravity fg=mg (directly down, where g=9.8m/s2). the normal force n (directly up). the force of static friction fs (directly left, opposing any potential motion). if we want to find the size of the force necessary to just barely overcome static friction (in which case fs=îľsn), we use the condition that the sum of the forces in both directions must be 0. using some basic trigonometry, we can write this condition out for the forces in both the horizontal and vertical directions, respectively, as: fcosî¸â’îľsn=0 fsinî¸+nâ’mg=0 in order to find the magnitude of force f, we have to solve a system of two equations with both f and the normal force n unknown. use the methods we have learned to find an expression for f in terms of m, g, î¸, and îľs (no n).
