PHYSICS MCQs (Set-3)
FOR JEE NEET Med/Engineering Entrance Examinations
Topics Covered: Kinematics (Motion in a Straight Line)
Q1: A particle starts from rest with uniform acceleration 'a' Its velocity after 'n' second is 'v'. The displacement in last two seconds is:
(a) 2v(n-1)/n
(b) v(n-1)/n
(c) v(n+1)/n
(d) 2v(2n+1)/n
Q2: A body starts from origin and moves along x-axis such that at any instant velocity is v = 4t³ - 2t. The acceleration of the particle when is it is 2m away from the origin is:
(a) 14 m/s²
(b) 18 m/s²
(c) 22 m/s²
(d) 32 m/s²
