The position of a body moving along x-axis at time t is given by x = (t2-4t+6) m . The distance travelled by body in time interval t = 0 to t = 3 s is? - (1) 5 m (2) 7m (3) 4 m (4) 3 m
1 Answer
(1)
Explanation:
We're asked to find the distance traveled by the object after the first three seconds of its motion, given its one-dimensional position equation.
Notice that it doesn't ask for the displacement of the particle, it asks for the total distance traveled. With that in mind, we can't simply plug in the
Since it's asking for the distance traveled, we can disregard the "
We can see that the particle traveled
so option (1) is correct.
