Q1:A large tank is filled with water. The pressure on the base of the fish tank is 4000N/m². The base of the tank is a rectangle

Ymorist [56]

Answer:

F = 36 kN

Explanation:

It is given that,

The pressure on the base of the fish tank is 4000N/m².

The base of the tank is a rectangle measuring 2.0m by 4.5m.

Area of the base of the tank is 9 m²

We need to find the force on the base caused by the base of the water. Pressure on the base of the tank is given by the force acting per unit area such that,

$P=\dfrac{F}{A}\\\\F=P\times A\\\\F=4000\times 9\\\\F=36000\ N\\\\F=36\ kN$

So, the force of 36 kN is acting on the base by the base of water.

A 700 kg racecar slowed from 30 m/s to 15 m/s. What is the change in momentum

Lerok [7]

Momentum = (mass) x (speed)

Original momentum = (700 kg) x (30 m/s) = 21,000 kg-m/s

Final momentum = (700 kg) x (15 m/s) = 10,500 kg-m/s

Change in momentum = - 10,500 kg-m/s .
