To determine the time taken by the ball to strike the surface of piston A, we only need to consider the vertical motion of the ball. Given: Initial vertical velocity, u_y = 0 m/s (since the ball is thrown horizontally). Vertical distance (height), h = 20 m. Acceleration due to gravity, g = 10 m/s^2 (standard approximation). We use the kinematic equation for vertical displacement: s_y = u_y t + (1)/(2) g t^2 Step 1: Substitute the given values into the equation. 20 m = (0 m/s) t + (1)/(2) (10 m/s^2) t^2 20 = 0 + 5 t^2 20 = 5 t^2 Step 2: Solve for t^2. t^2 = (20)/(5) t^2 = 4 Step 3: Solve for t. t = sqrt(4) t = 2 s The time taken by the ball to strike the surface of piston A is 2 s.
