The position of a body moving along x axis at time t is given by x=(t^2-4t+6)m.the distance travelled by the body in time interval t=0 to t=3s is

1. 5m
2. 7m
3. 4m
4. 3m

3m as when t = 0 , the value is 6 and when t=3 y value is 3 , the differnce is 3 , in the above eq , the answer is being multiplied by m so therefore 3m

ADITYAAMBILKAR: Your answer is wrong correct answer is 5m

sukulhanda01p3go2g: in view of a quadratic equation , we will take t=0 + t=(x value of vertex) + t= 3 , when t = 0 , x = 6 , when t = 2 , x = 2 (vertex of parabola), when t = 3 , x = 3 , which is equal to 6-2+1 = 5

sukulhanda01p3go2g: 5m in that case

sukulhanda01p3go2g: but if we take the direct distance ( displacement ) according to that its 3m

sadiya721: can u please tell how this calculation is??

sukulhanda01p3go2g: You can graph the parabola and find the distance

sadiya721: oohh thanks
