Question

the
f x = t ² - 4+² - 3t then find
distance travelled them
t =0
to t=45.​

Answer 1

Explanation:

put t=45 in equation and you will get your answer

Answer 2

Answer:

The correct option is A.

Given,

x=t2−4t+6

So, the change in velocity is:

dtdx=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
