As per your syllabus, if a ball is dropped from REST and falls for 2 s (g = 10 m/s²), what is its velocity at t = 2s?
A20 m/s downward (using v = gt)
B40 m/s
C10 m/s
D5 m/s
Answer & Solution
Correct answer: A. 20 m/s downward (using v = gt)
As per your syllabus, v = gt = 10 × 2 = 20 m/s downward.
The other options misapply.
