Question

Hello! I need help with these 2 calculus problems. Thank you!!

Answer 1

3. The velocity is given with including the air resistance.

And it is also given that acceleration due to gravity is 9.8 m/sq.s and upward is considered as the positive direction.

So the equation formed is

`\frac{dv}{d\text{ t}}=9.8-0.1v`

Hence the correct option is d.
