I'm not from that school but I can help you.
Answer:
Work done against gravity will be
W = Mgℓ
Explanation:
Work done to raise the mass from ground to given height is against gravity
So here work done is given by the formula

here we know that

it is the force due to gravity which is also known as weight
so here distance moved by the object is given as
d = ℓ
now work done is given as
W = Mg ℓ
<span>You want to focus on the car's acceleration.

Medicine to a patient. That should be calculated based on weight, strength/dosage and possibly other factors
