Step 1: Identify the given kinematic information. The object starts from rest, so its initial velocity is u = 0 m/s. The distance covered is s = 18 m. The time taken is t = 3.0 s. Step 2: Choose the appropriate kinematic equation. To find the acceleration (a) given u, s, and t, we use the kinematic equation: s = ut + (1)/(2)at^2 Step 3: Substitute the known values into the equation and solve for acceleration. 18 m = (0 m/s)(3.0 s) + (1)/(2)a(3.0 s)^2 18 = 0 + (1)/(2)a(9.0) 18 = 4.5a a = (18)/(4.5) a = 4 m/s^2 The acceleration of the object is 4 m/s^2.
