Explanation:
We know,
1KN = 1000N
Then, Force(F) = 5*1000N
=5000N
Here,
Power (P)=Work(W)/Time(T)
=Force * distance/ Time (W = F*s)
= 5000*15/75
=1000
So, The power of body or object is 1000Watt.

An unbalanced force.
Newton's first law states that an object in motion will stay in motion until a unbalanced force acts upon it.
Your speed when your car hits a fixed object is 60 mph.
The given parameters:
- Your initial speed, v = 60 mph
<h3>What is relative velocity?</h3>
Relative velocity tells us how fast we are traveling from a fixed point or reference point.
- When travel at 60 mph in a car, you are moving at the same rate with the car.
- If you are not wearing a seat belt, when you hit a fixed object, you will move forward at the same rate as the car's speed.
Thus, we can conclude that your speed when your car hits a fixed object is 60 mph.

Answer:
Net force is Zero.
Explanation:
If all forces that are equal and opposite are exerted on an object the resulting force will be Zero.
Answer:
density of water is much greater than density of air
Explanation:
when body is in fluid it carries weight which is always equal to upthrust
upthrust is given as
upthrust= density of fluid ×strength of gravitational field g × volume of body in fluid
as volume of ship and aeroplane is same and strength of gravitational field or acceleration due to gravity is same hence upthrust depens upon density of fluid .
density of air is about 1.2 kg/m^3 and density of water is 1000kg/m^3 hence ship carries more load
