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,
So, the force of 36 kN is acting on the base by the base of water.
Option a) 0.8 m/s² is the correct answer
the acceleration of the motorcycle is 0.8 m/s²
Given the data in the question;
Since the motorcycle stopped then, initial speed u = 0 m/s
final speed v = 12 m/s
time t = 15 s
acceleration = ?
To get our acceleration, we use the first equation of motion.
This equation states that;
so, we simply substitute in our given values
so we find a
Therefore, the acceleration of the motorcycle is 0.8 m/s²
Option a) 0.8 m/s² is the correct answer
