A ship travels north at 15 km/h for 5 h. What is the ship's displacement in km?
2 answers:
Answer:
Displacement, d = 75 km
Explanation:
Given that :
The speed of the ship is 15 km/h. It travels for 5 h.
To find :
The displacement of the ship
Solve :
Let d is the displacement of the ship. It can be calculated using the definition of velocity. The total displacement per unit time is called the velocity of an object.
On rearranging,
d = 75 km
Therefore, the ship's displacement is 75 km.

Explanation:
It is given that,
Mass of the woman, m₁ = 52 kg
Angular velocity,
Mass of disk, m₂ = 118 kg
Radius of the disk, r = 3.9 m
The moment of inertia of woman which is standing at the rim of a large disk is :
I₁ = 790.92 kg-m²
The moment of inertia of of the disk about an axis through its center is given by :
I₂ =897.39 kg-m²
Total moment of inertia of the system is given by :
I = 1688.31 kg-m²
The angular momentum of the system is :
So, the total angular momentum of the system is 4980.5 kg-m²/s. Hence, this is the required solution.
