Question

A particle moves along X-axis in such a way that its coordinate X varies with the time t according to the expression x = (8 - 5t + 8t²) meter. The initial velocity of the particle is:
Options
A -5 m/s
Correct Answer
B 8 m/s
C -8 m/s
D +16 m/s
Correct Answer

Option A is the correct answer.

Detailed Explanation

Velocity v = dx/dt = -5 + 16t. At t=0 (initial), v₀ = -5 m/s.

Hint

Differentiate the position function with respect to time to find velocity, then evaluate at t=0.
