A simple pendulum is made from a bob of mass 0.04 kg suspended on alight string of length 1.4m. Keeping the string taut, the pendulum is pulled to one side until it has gained a height of

(a) M g H, where H = 0.1 m, M = mass and g = acceleration of gravity

(b) If amplitude (A) is the maximum horizontal displacement, then
A = sqrt[1.4^2 - 1.3^2] = 0.52 m
(c) (2 pi)*sqrt(L/g)
where L = 1.4 m
(d) A*sqrt(g/L)
(e) M g H (same as maximum energy)

To answer a question about a simple pendulum, we need to use some basic principles of physics. One of the key principles is conservation of energy, which states that the total energy of a system remains constant as long as no external forces are acting on it.

In the case of a pendulum, the total energy is made up of two components: potential energy and kinetic energy. Potential energy is the energy possessed by an object due to its position or height above a reference point, while kinetic energy is the energy possessed by an object due to its motion.

Now, let's solve the given problem step by step:

1. First, determine the initial potential energy of the pendulum. Since the bob is pulled to one side, it gains a height. The potential energy (PE) of the pendulum at this point is given by the formula PE = mgh, where m is the mass, g is the acceleration due to gravity (approximately 9.8 m/s^2), and h is the height.

Given:
- Mass (m) = 0.04 kg
- Height (h) = Unknown

2. Next, we need to find the value of the height gained by the bob. Unfortunately, the problem statement is incomplete, and the height gained by the bob is not provided. Without this information, we cannot calculate the potential energy at the highest point.

Therefore, it is not possible to solve the problem with the given information. You would need to provide the height gained by the bob in order to proceed with the calculation.
