Question

the position of a body change by given equation x=t(t-1) find 1.velocity when Displacement is 0 2.distance and displacement travelled by body in t=2sec 3.v-t and speed time

Answer 1

Answer:

5 m

Explanation:

Given,

x=t 2−4t+6

So, the change in velocity is:

dt dx=2t−4

Since velocity is changing,

At t=0,x1=6

At t=2,x2=2

So the magnitude of the distance traveled is:

6−2=4m

At t=3,x3=3

So distance traveled from t=2s to t=3s

x3−x2=3−2=1m

Thus the total distance is:

4+1=5m

Hope this answer helps you
