Conservation of energy
Homework Answers
Change in Potential energy = mgh = 4*9.8*8(1+sin30) = 470.4J
Therefore kinetic energy of mass at the lowest point = 0.5mv^2 = 470.4
v^2 = 470.4*2/4 = 235.2
Tension = mg + mv^2/l = 4*9.8 + 4*235.2/8 = 156.8 N

A massless rigid rod whose length L = 21.0 cm has a ball of mass
m = 0.079 kg attached to one end (see Figure). The other end is
pivoted in such a way that the ball will move in a vertical circle.
The system is launched from the horizontal position A with an
initial downward speed v0. The ball just reaches point D
and then stops. Calculate v0.

4. A small object of mass M is swinging around in a vertical circle held by a massless string of length L, attached to a pivot, as shown. Given that the speed of the mass at the bottom of the circle is Vo, find the tension in the string when the mass is at an angle (theta) with respect to the vertical (see figure) Pivot M
