Question

A car is moving on straight line, its position time relation is given as x = (4t+3) (where t is time in s), then which one statement is incorrect?

Particle is in uniform motion

Particle is not at origin at t = 0 s

Particle has negative velocity

Displacement of the particle is 12 m in first 3 S​

Answer 1

Given, x=4t+3

We know, dx/dt=velocity

Velocity=4+0(Differentiating with respect to t)

V=4m/s

So, it is in uniform velocity(Option A is correct)

At t=0

x=4x0+3=3

Clearly, it is not at origin(Option B is correct)

Particle can have negative velocity.

Dispalcement of the particle in t=3s is 4x3+3=15m

So, last option is incorrect
