A 0100 kg block is suspended from a spring when a small, Ask an Expert

Academics

A 0.100 kg block is suspended from a spring. When a small pebble of mass 40 g is placed on the block, the spring stretches an additional3.8 cm. By the pebble on the block, the block oscillates with amplitude of 15.0cm. (Suppose that the pebble is glued to the block.)

1. What is the frequency of the motion?

2. How long does the block take to travel from its lowest point to its highest point?

3. What is the net force on the pebble when it is at a point of maximum upward displacement?
