If a particle moves such that the displacement (s) is proportional to the square of the velocity (v), then its acceleration (a) is
Options
- Aproportional to s^2
- Bproportional to 1/s
- Cproportional to 1/s^2
- Da constant
Correct answer
D. a constant
Step-by-step solution
Given s v^2 s = k v^2 where k is a constant. Differentiating both sides with respect to time t : ds dt = 2kv dv dt Since ds dt = v and dv dt = a : v = 2kv a a = 1 2k Since k is a constant, acceleration a is a constant. Answer: a constant
