Question

A raft is made of plastic block with a density of 650kg/m3, and its dimensions are 2.00m x 3.00m x 5.00 m. What is the rafts apparent weight in water and the buoyant force on the raft in the water?

Answer 1

For the answer to the question above
The

Apparent weight = *assumption: the raft is floating so, therefore, it is zero

for Fbuoyant let us use this equation to solve the problem
Fbuoyant= -density x volume x gravity
= - 650 x 24 x -9.81 =
So the answer is
153,036 Kgms^-2
I hope my answer helped you.
