we are given
position function as
we know that acceleration is second derivative of position
so, firstly, we will find first derivative
now, we can simplify it
now, we can find derivative again
now, we can plug t=2
and we get
so,
the value of the person’s acceleration a at t=2s is -4..........Answer

The radius of the circle is
, which is 4
The center of the circle is at (0,10)
Answer:
The answer is 40 inch.
Here it is already said that they are similar so
12/30 = 16/PQ
12PQ = 30*16
PQ = 480/12
THEREFORE PQ = 40 INCH.
