Question

A ferry boat is 2.0 m wide and 4.0 m long. When a truck pulls onto it, the boat sinks 2.00 cm in the water. What is the weight of the truck?DENSITY OF WATER IS 1000 Kg/m^3

Answer 1

Answer:

156,800 N

Explanation:

Given: Width = 2.0 m Length = 4.0 m Depth =  2.00 cm. Density of water = 1000 Kg/m³

To find: What is the weight of the truck?

Formula: $F = m$ × $9.8 m/s^2$

Solution: Weight is a measure of the force of gravity pulling down on an object. It depends on the object's mass and the acceleration due to gravity, which is 9.8 m/s² on Earth. F is the object's weight in Newtons (N) and m is the object's mass in kilograms.

Firstly, multiply the length, width, and depth.

$2.0$ × $4.0$ × $2.00$ $= 16$

Next, the weight of the truck is found by multiplying the density of water, the result found by multiplying the length, width, and depth, and the formula;

$1000 kg/m^3$ × $16$ × $9.8m/s^2$$= 156,800$

Therefore, the weight of the truck is 156,800 N
