The answer for your question is C
Try to find the lowest common denominator. In this case it's 28, which makes our numbers as follows:
1/4 = 7/28
1/7 = 4/28
7/28 + 4/28 = 11/28
We can't simplify it so that's the result.

Answer:
s = 6 m
Step-by-step explanation:
The value of the velocity v is given as:
m/s
To find s, we have to integrate and apply the initial values of s = o when t = 0:

When t = π/2, s will be:
s = -3cos(2 * π/2) + 3
s = -3cos(π) + 3
s = -3(-1) + 3
s = 3 + 3
s = 6 m
