Question

5.A pendulum with string length 1.2m is dropped from rest. If the mass at the end of the pendulum is 2.03kg, what is its initial potential energy?​

Answer 1

Answer:

mass - 2.03 kg

height. -. 1.2 m

g. -. 10 m/s2

Explanation:

Potential energy = mgh

2.03 * 1.2 * 10

2.03 * 12

24. 36 joules

Answer 2

Answer:

the initial potential energy is = 23.87 joules

Explanation:

body suspended from a fixed point so as to swing freely to and fro under the action of gravity and commonly used to regulate movements

given

length of the string =h=1.2m

mass of the object m =2.03kg

acceleration due to gravity g = 9.8m/s²

potential energy

the potential energy is the energy accumulated in an object by its location

PE=mgh

where m=mass

          g= acceleration due to gravity

          h= hight

PE=2.03x 9.8x1.2

    =23.87 joules

the initial potential energy is = 23.87 joules
