Rocket Ship has to do a lot with air. If i'm right, they calculate the area, weather, about the air.
A ball gets throwed in the air, which gravity comes into place.
Basketball is also a similar example to a ball.
Answer:
Explanation:
Given
mass of children
distance between two children
suppose small child is at a distance of x m from pivot point
so torque of small child and heavier child must be equal
Answer:
D
Explanation:
From the information given:
The angular speed for the block
Disk radius (r) = 0.2 m
The block Initial velocity is:
Change in the block's angular speed is:
However, on the disk, moment of inertIa is:
The time t = 10s
∴
Frictional torques by the wall on the disk is:
Finally, the frictional force is calculated as:
Pretty sure it’s A. Hope this helps.
<span>An imaginary line perpendicular to a reflecting surface is called "a normal" (principle line)
So, Your Answer would be Option B
