(4%) Problem 21: In a particular Cartesian coordinate system, a particle has coordinates x(t) = 2sin(31) + C, y = 0, z = 0, Caba PEPTE where t is in seconds, x is in meters, and C is a constant to be determined by the data. At t=0 the particle was at x = 1 m. Forbes, David - david.forbes@doane.edu DA 14% Part (a) Find the value of constant C, in meters.
