## Law of Conservation of Energy Problems with Solutions

Problem 1:

An intrepid physics student decides to try bungee jumping. She obtains a cord that is m long and has a spring constant of . When fully suited, she has a mass of . She looks for a bridge to which she can tie the cord and step off. Determine the minimum height of the bridge L, that will allow her to stay dry (that is, so that she stops just before hitting the water below). Assume air resistance that is negligible.

## Speed of Falling Object Problem

An object that has a mass of m kg was thrown straight up from a platform which is h m above the ground. The initial velocity was

The air resistance is proportional to the velocity of the object and is equal to av N. Write down the equation for the distance traveled by the object at any time. Find the velocity of the object at the ground level for

## Rotational Motion Examples

Problem 1:
Instead of moving back and forth, a conical pendulum moves in a circle at constant speed as its string traces out a cone (see figure below). One such pendulum is constructed with a string of length and bob of mass . The string makes an angle with the vertical.

## Motion Physics Examples Solved

Consider a simple model for a rocket launched from the surface of the Earth. A better expression for a rocket’s position measured from the center of the Earth is given by:

where RE is the radius of the Earth (6.38 ✕ 106m) and g is the constant acceleration
of an object in free fall near the Earth’s surface (9.81 m/s2). Continue reading

### Classical mechanics

Problem statement

Particles with two different masses m and M are located along a linear harmonic chain
of infinite length. The chain has a force constant k (see the picture below). The
distance between two particles with the same mass is equilibrium and equals to a.
qj and rj are the deviations of particles mj and Mj from their equilibrium positions respectively. Continue reading
