Answer:
Hey
Your answer would be D (Aristotle stated that heavy objects fall faster than light objects). He thought be comparing a feather falling to a rock falling that you could see that heavier objects fall faster than light ones. of course now we know that all objects fall at the same speed and that weight does not affect that. only air drag affects how fast objects fall.
- Initial velocity (u) = 10 m/s
- Final velocity (v) = 22 m/s
- Time (t) = 12 s
- Mass (m) = 200 Kg
- Let the acceleration be a.
- By using the equation of motion,
v = u + at, we have
- 22 m/s = 10 m/s + 12 s × a
- or, 22m/s - 10 m/s = 12 s × a
- or, 12 m/s = 12 s × a
- or, a = 1 m/s^2
- Let the force be F.
- We know, F = ma
- Therefore, the force on the accelerated object (F)
- = ma
- = (200 × 1) N
- = 200 N
