Question

The position of a body moving along x-axis t time t is given by x=(t(t)-4t+6). The distance traveled by the body in time interval t=0 to t=3s is

Answer 1

at time t=0 the position of the body is x=0²-²4*0+6=6 which is the initial position of body.at time t=3s the position is 3²-4*3+6=3so the distance travelled is l3-6l=3
