Larry Finkelstein, Norman Fischer, and Cassius Schwartz have been overlooked, in my opinion.
Torque [Nm] = Force [N] x Force arm [m]
C=F*b=20*0.20=4 Nm
The correct answer is C
Answer:

(a) The maximum height reached by Jane is 1.8 m.
(b) The length of the vine will affect the time of her motion, which will impact on speed and maximum height attained.
<h3>
Maximum height Jane can swing</h3>
apply the principle of conservation of energy;
P.E = K.E
mgh = ¹/₂mv²
h = v²/2g
where;
- v is speed of jane
- g is acceleration due to gravity
h = (6²)/(2 x 9.8)
h = 1.84 m
<h3>Time of motion of Jane</h3>
Assuming Jane to be in simple harmonic motion, the time of motion is calculated as;
T = 2π√(L/g)
where;
- L is the length of the vine
Thus, the length of the vine will affect the time of her motion, which will impact on speed and maximum height attained.

Answer:
Kinetic energy is not made; it is a result of energy transformation
Explanation:
Let's discuss what happens to the ball when it is on top of the mountain and rolls down.
Initially the ball has a total mechanical energy, which at this point is potential.
Em₀ = U = mg h
When the ball starts to roll down, part of this potential energy will be transformed into kinetic energy.
Em = K + U = ½ m v² + mg y
but mechanical energy is conserved.
The presence of the grass introduces a force in the opposite direction that creates a friction force work (not conservative), for which the total mechanical energy decreases
W_{friction}= Emf - Emo
When examining the answers, the one that best describes Lana's error is:
Kinetic energy is not made; it is a result of energy transformation
