Given mass = 2kg, height = 1.2m,g = 9.8.

We know that Work done W = FD

= > W = (mg)(D)

= > W = (2 * 9.8)(1.2)

= > W = 23.52 Joules.

The distance is 22.45 cm.

Explanation:

Height of cylinder, H = 14 cm

depth of hole, h = 5 cm

The distance of landing of stream from the base of cylinder is

R = 2\sqrt{H(H-h)}\\\\R = 2\sqrt{14(14-5)}\\\\R = 22.45 cm
