The player must give a speed of 12.66 m/s to the ball.

Explanation:

Since, the ball is released at the same height as the basket. Therefore, this is a complete projectile motion, with following parameters:

Horizontal Range = R = 16 m

Launch Angle = θ = 51°

Launch Speed = V = ?

The formula for horizontal range of projectile is:

R = V² Sin 2θ/g

V² = Rg / Sin 2θ

V² = (16 m) (9.8 m/s²) / Sin 2 (51°)

V = √160.3 m²/s²

V = 12.66 m/s
