Question

The V - t graph is shown in the figure for particle the (V m/s) acceleration of particle is

(A) 22.5 m/s²

(B) 5 m/s²

(C) -5 m/s²

(D) -3 m/s²

Answer 1

Correct option is (B) 5 m/s²

Let u is the initial velocity and v is the final velocity. Acceleration produced is given by

\(a = \frac{v - u}{t}\)

From the graph,

u = 0

v = 15m/s

a = \(\frac{15}3\)​ = 5m/s²
