Option B: 1.6 s.
Although the equation is not included, you can obtain it by physical considerations
H(t) = -16.t^2 + 52t + 16
The maximum point is at the vertex and the vertex is in the middle of the roots.
The roots are when H(t) = 0,
So you have to solve 0 =-16t^2 + 52t + 16
Use the quadratic formula and you will find t = 3.53 and t =-0.28
Then the vertex is at the middle point = (3.53 -.028)/2 =1.63 s and the answer is option B: 1.6 s.

I assume that the last question should read "cosE"
The answer you be five. If you take the twenty tokens and divide them into groups of four, you will find that you are left with five groups of tokens. Each group of tokens represents an hour of parking time. This will give you five groups, or five hours, total.
