Question

The velocity of a particle moving along a line is t2 - 2t sin(t2 ) meters per second. The net change in the particle's position during the time interval 0 ≤ t ≤ 4 is given by:

Answer 1

Answer 2

Velocity is the first derivative of the position function, so to go from velocity to displacement, take the integral of the velocity function using the boundaries given in the problem (t = 0 to t = 4)
