1. A pendulum consists of a mass m = 0.080 kg hanging from a flexible string of length L. The string is very thin, very light, and doesn't stretch much. It makes small oscillations, with a period of 0.663 s. Find the oscillation frequency of the pendulum. Neglect any air resistance.
(in Hz)
2. Find the period of the same pendulum on the moon's surface. The gravitational acceleration of the moon is 1.67 m/s2.
(in s)

A 48.9 kg pole vaulter running at 13.0 m/s vaults over the bar. Assuming that the vaulter's horizontal component of velocity over the bar is 1.7 m/s and disregarding air resistance, how high was jump.
A certain freely falling object, released from rest, requires 1.90 s to travel the last 36.5 m before it hits the ground. Find the total distance the object travels during the fall
What would be the potential difference VC - VB across the thin resistor if the battery emf is 4.00 volts? Suppose that the electric field in the thick wires is very small (so that the potential differences along the thick wires are negligible)
There is a uniform magnetic field present, given by B=0.003i + 0.004j + 0.002k, where i, j, k are the unit vectors along the cartesian coordinate axes') in units of Tesla. Compute the y-component of the magnetic force acting on a segment of wire ..
