028. A body is moving with velocity 30m/sec towards each. After 10seconds its velocity becomes 40m/s towards north. Find its acceleratioa) 1m/sec b) 7m/sec cV7 m/sec d) 5m/sec |

Answer» Initial velocity = The velocity in east direction = 30i , where i is unit vector along x axis. Final velocity = The velocity in north direction = 40j , where j is unit vector along y axis. Average acceleration = { (root over(30^2+40^2))/10} m/s2 = 5 m/s^2 in north east direction! |
