Answer:
180 in
Step-by-step explanation:
The perimeter is just the sum of the lengths of the sides of the shape.
So all we need to do here is:
40+10+(40-18)+(50-10)+18+50.
I got (40-18) for the bottom of the top rectangle, the part that is poking out.
I got (50-10) for the right side of the rectangle that is poking out towards the bottom.
40+10+(40-18)+(50-10)+18+50
40+10+22 +40 +18+50
50 +62 +68
50+62+68
112+68
180
180 in
I'm going to post a drawing here to show the lengths I was talking about:

Step-by-step explanation:
From the question we are told that
The acceleration is
The velocity at t = 0 is
The position at time t = 0 is
Generally acceleration is mathematically represented as
=>
=>
integrating both sides we have
=>
Now at t = 0
=>
So
Generally the position of the body is mathematically represented as
So
So
Now at t = 0
