Answer:
The energy lost is 0.333156518 J.
Explanation:
The given mass of the pendulum = 0.259 kg
Length = 0.97 m
Displaced at an angle of = 31.4 degrees
Maximum angle of swing = 10 degrees
Initial potential energy = mgh
Initial potential energy = 0.259 × 9.8 × (1 – cos31.4)
= 0.259 × 9.8 × ( 1- 0.853551)
= 0.371716852 J
Final potential energy = mgh
Final potential energy = 0.259 × 9.8 × (1 – cos10)
= 0.259 × 9.8 × (1 – 0.984808)
= 0.0385603344 J
The lost energy = Initial potential energy - Final potential energy
= 0.371716852 J - 0.0385603344 J
= 0.333156518 J
Answer:
I mean this is what I think
Explanation:
you would need to place a rock on top of each other until you reach the ceiling
It seems logical to me
