Question

The base area of a boat is 4m*m . A man weighing 86kg weight steps in to the boat. Calculate the depth into which the boat sinks further into water

Answer 1

Answer:

h = 21.5 mm

Explanation:

Let us first calculate the force exerted by man on boat;

W = m x g;

W = 86 x  10

W = 860N

Hence this much weight is applied on the boat, now the boat will offer equal but opposite force;

W  = p g h

Putting the values;

860 = h x 10 x 4 x 1000

86 = h x 4000

h = 86/4000

h = 21.5 mm
