Question

The diagram shows a raft floating on water.

A force of 20,000N acts on the raft in the direction of the arrow shown in the
diagram.
(a)State the name given to the force shown in the diagram.
(b)Calculate the mass of the raft.

Answer 1

Answer:

a) Gravitational force

b) To calculate mass of Raft.

$w = m \times g$

$\because \: Force = Weight$

$\sf \displaystyle\therefore \: m = \frac{w}{g}$

$\sf \therefore \: m = \dfrac{20000}{9.77}$

$\sf \therefore \: m = 2047.08 \: kg$

Therefore mass is 2047.08 kg
