no problem it's okay if you need any problem then ask
Yes. The line is increasing. The flat line at the top of the graph is where there is not acceleration and the decreasing line is deceleration.
Answer with Explanation:
We are given that


Differentiate x and y w.r.t t





Substitute t=1


Magnitude of velocity=

Hence, the magnitude of the missile's velocity=16.49 m/s


Substitute t=1



Hence, the magnitude of acceleration when t=1 s=
The next step is -748 divide by -11 is 68 m (answer) the pic got cropped sorry
