**Problem to Solve:**At time \( t \), the position of a body moving along the s-axis is given by the equation:\[ s = t^3 - 21t^2 + 120t \, \text{m} \]Find the body's acceleration each time the velocity is zero.**Options:**- a(10) = 0 m/sec\(^2\), a(4) = 0 m/sec\(^2\)- a(10) = 18 m/sec\(^2\), a(4) = -18 m/sec\(^2\)- a(20) = 120 m/sec\(^2\), a(8) = 20 m/sec\(^2\)- a(10) = -18 m/sec\(^2\), a(4) = 18 m/sec\(^2\)(Note: This problem involves finding where the velocity, derived from the position function \( s(t) \), is zero, and then calculating the acceleration at those points.)
