Question

A particle is moving along a straight line whose velocity - displacement graph is shown in figure. What is the acceleration when displacement is 3 m?

A. `-4sqrt(3) ms^(-2)`
B. `3sqrt(3) ms^(-2)`
C. `sqrt(3) ms^(-2)`
D. `4//sqrt(3) ms^(-2)`

Answer 1

Correct Answer - A
a. `a = v(dv)/(dx) = 4 xx (-tan60^@) = -4sqrt(3) ms^(-2)` .
