Question

At any instant, the velocity and acceleration of a particle moving along a straight line v and a. The speed of the particle is increasing if

• A. v > 0, a > 0
• B. v < 0, a > 0
• C. V > 0, a < 0
• D. v > 0, a = 0

Answer 1

The correct option is A v > 0, a > 0

acceleration of fan must be incensing in order to gain speed. if acceleration is increasing then velocity also increases.
