Question 3 / 10

A particle moves with v = 4t² m/s. Its displacement after 3 seconds is:

A12 m
B36 m
C48 m
D64 m
Class 11 · Physics · Kinematics✓ Correct +2

A particle moves with v = 4t² m/s. Its displacement after 3 seconds is:

B36 mYour answer ✓
Why

Displacement = ∫₀³ 4t² dt = [4t³/3]₀³ = 4·27/3 = 36 m. Integrate velocity over time — don't multiply v by t when v isn't constant.
