Given: Initial velocity, u=0~m/s (starts from rest). Acceleration, a=2~m/s^2. Distance travelled, s=9~m. Use the kinematic equation: v^2 = u^2 + 2as Step 1: Substitute the known values. v^2 = (0~m/s)^2 + 2(2~m/s^2)(9~m) Step 2: Simplify inside the parentheses first. v^2 = 0 + 2 × 2~m/s^2 × 9~m v^2 = 36~m^2/s^2 Step 3: Solve for v (take the positive root for magnitude). v = sqrt(36~m^2/s^2) v = 6~m/s 6 m/s
