Question

12. The motion of a particle along a straight line is described by the equation x=6+4' t' where
x is in meters and t in seconds Find the position, Velocity and acceleration of the particle at t=2
seconds.

​

Answer 1

For position put x=2

X=6+4*2

X=6+8

14

On differentiating the given equation with respect to students we will get

dx/dt=6+4t/dt (differentiation of constant is0)

V=4

Hence velocity is independent of time and a=0 by further differentiating the equation.

dv/dt=4dt

A=0
