, Q 1.
Physicsaholics
Starting from rest a particle moves in a straight line with acceleration
a= {2 + t -2} m/s2
Velocity of particle at the end of 4 s will be
(A) 16 m/s (B) 20 m/s (C) 8 m/s (D) 12 m/s
Q 2. Velocity versus displacement graph of a particle moving in a straight line is as shown in
figure.
The acceleration of the particle is
(A) constant (B) increases linearly with x
(C) increases parabolically with x (D) none
Q 3. An object is tossed vertically into the air with an initial velocity of 8 m/s. Using the sign
convention upwards as positive, how does the vertical component of the acceleration 𝑎𝑦 of
the object (after leaving the hand) vary during the flight of the object?
(A) On the way up ay > 0, on the way down ay > 0
(B) On the way up ay < 0, on the way down ay > 0
(C) On the way up ay > 0, on the way down ay < 0
(D) On the way up ay < 0, on the way down ay < 0
Q 4. The relation between time t and distance x is t = x2 + x where and are constants. The
retardation is: (if v is velocity of the particle)
(A) 2 v3 (B) 2 v2 (C) 2 v2 (D) 2 2v3
Q 5. Acceleration versus time graphs for four objects are shown below. All axes have the same
scale. Which object had the greatest change in velocity during the interval?
(A) (B)
