Answer:
The total mechanical energy of a pendulum is conserved neglecting the friction.
Explanation:
- When a simple pendulum swings back and forth, it has some energy associated with its motion.
- The total energy of a simple pendulum in harmonic motion at any instant of time is equal to the sum of the potential and kinetic energy.
- The potential energy of the simple pendulum is given by P.E = mgh
- The kinetic energy of the simple pendulum is given by, K.E = 1/2mv²
- When the pendulum swings to one end, its velocity equals zero temporarily where the potential energy becomes maximum.
- When the pendulum reaches the vertical line, its velocity and kinetic energy become maximum.
- Hence, the total mechanical energy of a pendulum as it swings back and forth is conserved neglecting the resistance.
Answer:
993 m or 3257 ft
Explanation:
The captain was told to fly at at 1500 ft altitude. At the rate of 3.28 ft to 1 m, this is
metres.
Since he was at 1450 m, he thought he was above the correct altitude by
1450 - 457 = 993 m.
In feet, this is
993 * 3.28 = 3257 ft
