An object's position is defined by: r = [0.8sin(2t)i+0.6cos(2t)j+0.3k]ft What is the magnitudes of the velocity and acceleration of the object when t = 1.3 s?

Position is defined byR = 0.8 sin(2t) i + 0.6 cos(2t) j + 0.3kVelocity is given byV = dR/dtV = 1.6 cos(2t) i – 1.2 sin(2t) jAt t = 1.3V = 1.6 cos(2.6) i – 1.2 sin(2.6) jV = -1.37i –...
