Given a model that looks like that, I do experience severe upset. I'm not throwing up yet, but it's only a matter of time.
Answer:
<em>7.45 10^5N.</em>
Explanation:
according to newtons second law of motion;
Fapp is the applied force
Fr is the resistive force
m is the mass of the luxury
a is the acceleration
Since the huge luxury liner move with constant velocity, then acceleration is zero i.e a = 0. The equation becomes;
This shows that the applied force will be equal to the resistive force if the velocity is constant.
Given Fr = 7.45 10^5 N therefore the resistive force will also be 7.45 10^5N.
<em>Hence the magnitude of the resistive force exerted by the water on the cruise ship is 7.45 10^5N.</em>
A
the unit used for measuring both work and energy is the joule
Answer:
Part a)
F = 0.735 N
Part b)
Explanation:
As we know that mass of the cube is given as
Now we know that cube is floating in the water
So net force due to weight of the cube must be counter balanced by buoyancy force on the liquid
so we have
Part b)
Percentage of volume submerged into the liquid is given as
now percentage of submerged liquid is given as
The mass of the car at the given kinetic energy is 920 kg.
The given parameters;
- initial velocity of the car, u = 22 m/s
- kinetic energy of the car, K.E = 222,640 J
Kinetic energy if the energy acquired by a body during its motion. This kinetic energy is the product of average velocity squared and mass of the object.
The mass of the car at the given kinetic energy is calculated as follows;
Thus, the mass of the car at the given kinetic energy is 920 kg.
