The position of an object undergoing a SHM is given as x(t) = 20 cos (nt + 7/3) cm. The position of the object in cm at t = 1s is approximately Drag answer here 20.0 cm The phase of the motion in radians at t = 2 s is approximately Drag answer here 1.0 m/ $2 The acceleration of the object at t = 1.0 s is approximately Drag answer here None of these 7:/3 radians -1.97 m/s2 J 3 rads 20 cm -10 cm
