Class 12 Physics Mechanics Kinematics

A particle moves along x-axis and its acceleration at any time t is a = 2 sin ($πt)$, where t is in seconds and a is in m/$s_{2}$ . The initial velocity of particle (at time t = 0) is u = 0.

Q. Then the magnitude of displacement (in meters) by the particle from time t = 0 to t = t will be :
