. A ball leaves a horizontal table with velocity v0 = 5 m/s.

A ball leaves a horizontal table with velocity v₀ = 5 m/s. The ball bounces elastically from a smooth vertical wall at a horizontal distance D (= 8m) from the table, as shown in figure. The ball then strikes the floor a distance x₀ from the table (g = 10 m/s²). The value of x₀ is

(a) 6 m                        (b) 4 m

(c) 5 m                        (d) 7 m
