Q.11
Single Correct Option, Marks: +4,-1
Position (in m) of a body moving along x-axis x = t-é? where t is in ‘sec'. Find the ratio of initial
velocity and initial acceleration at t=0 (in sec.)
(A) 1
(B) -1
(C) 2
(D) -2​

Answer 1

Answer:

Given,

s=t62−4t+6

So, the velocity of the particle changing,

v=

dt

ds

2t−4

Velocity is changing at t=3s

So,

At t=0s,s=6m

At t=3s,x=3s

So the distance traveled is:

6m−3m=3m
