Video-enhanced Physics Problems - Oscillations |
| 1. A car of mass, m, is placed on a straight track such that it rolls with
negligible friction. The car is placed between two springs, each of spring
constant k, that are attached to opposite ends of the track as shown. If the
car is pulled back along the track and released such that it oscillates in
simple harmonic motion, what is the angular frequency of the car's
oscillation? If the mass of the car is increased, does the period of oscillation increase, decrease, or remain the same? |

| 2. A mass hangs vertically on a spring. When it is pulled downward and released, it oscillates in simple harmonic motion. If it takes 0.40 seconds to travel from its lowest position to its highest position, its frequency of oscillation is |
