3. A pendulum is released from an initial height 83.0 cm (a) above its lowest point. It then swings down to its lowest point (b), where it contacts a horizontal rod that interrupts its motion and causes it to swing upward with a new radius, as shown below. The highest point it can swing to is 78.2 cm (c). What will be its speed at tha point?

Alice launches a pendulum from a point that is a height h above the lowest point by giving the bob an initial velocity directed upward along the trajectory. Bob decides to launch the pendulum from the same position at the same speed but directed downward along the trajectory. Whose launch will cause the pendulum to reach a higher highest point? Briefly explain your answer.

A pendulum is attached to the cart that has a mass of 3m and that is free to move along the horizontal direction. From the rest condition, when the lumped mass m of the pendulum makes a 0 angle with the vertical, the pendulum is released. 3m L m Compared to the case in which the cart is fixed (it cannot move), when 0=0°, the speed of the lumped mass at the tip of the pendulum would be smaller. (Vcartmoves...

A simple pendulum has a length L and a mass m. At its highest point, the pendulum mass is 0.25L above its lowest point (see figure below). What is the speed of the mass when it is at its lowest point? Express your answer in terms of m, L, and g. v = The position of a mass-on-a-spring oscillator is given by y = A sin(20t), where the value of t is in seconds and A = 0.44 m. What...
