A particle of mass m starts from x subscript o = 0 m with V subscript o > 0 m/s. The particle experiences the variable force F subscript x = F subscript o sin (cx) as it moves to the right along the x-axis, where F subscript o and c are constants.

I have answered the first 3 of 4 questions correctly and keep getting a message of format error in the last problem.

(1)The units of F (subscript o) = N

(2)The units of c = m^-1

(3)At what position x (subscript max) does the force first reach a maximum value? pi/2c

(4)What is the particle's velocity as it reaches x (subscript max)? Give your answer in terms of m, v (subscript o), F (subscript o), and c?
