IT, let's knock this out. a) Calculate the velocity at which the ball hits the court. Step 1: Resolve the initial velocity into horizontal and vertical components. The initial velocity is u = 60 \, m/s at an angle = 10^ to the horizontal. The horizontal component (u_x) remains constant throughout the flight. The vertical component (u_y) is affected by gravity. u_x = u = 60 \, m/s × (10^) ≈ 59.088 \, m/s u_y = u = 60 \, m/s × (10^) ≈ 10.419 \, m/s Step 2: Determine the final vertical velocity component (v_y). We use the kinematic equation v_y^2 = u_y^2 + 2as_y. Taking upward as the positive direction: The acceleration due to gravity is a = -g = -9.8 \, m/s^2. The vertical displacement
