Situation #3: A weight concentrated at the end
of a cord forms a conical pendulum for which t
period is 1.250s. Determine the velocity v of the
weight if the cord rotates inclined at 32° with th
vertical.
Situation #4: At the bottom of a loop the speed
of an airplane is 650kph. This causes a normal
acceleration of 8g m/s. Find the radius of the
loop.
Situation #5: The body rotates according to the
relation a = 4t, where a is in rads/s and t in sec
When t 0, o = 2 rads/s and 0 0. Determine:
a-the values of o and 0 when t = 3s.
b-the initial velocity.
c- the o-a and the 0-a equations.
