An insect start moving from origin at a constant velocity of 2i+3j for one second and then with constant velocity 2i + 2j for half second the distance of the insects from origin after these displacement is a) 4m b) 5m c) 7m d) 10m
coordinate after 1 sec = (2*1, 3*1) = (2,3)coordinate after one and half sec = (2+ 2*1/2, 3 + 2*1/2) = (3,4)So distance from origin = mHope it clears.
