Answer:
9.412 rad/s.
Explanation:
Velocity is the rate of change of an object's position.
V = x/t
Where x is the distance in m
= 2.4 m
t is time taken in s
= 8.5 s
V = 2.4/8.5
= 0.2824 m/s.
Equating linear velocity and angular velocity,
V = ω*r
Where,
ω Is the angular speed in rad/s
r is the radius of the circle in m
= 3 cm
= 3cm * 1m/100 cm = 0.03 m
ω = V/r
= 0.2824/0.03
= 9.412 rad/s.
<u>Answer:</u>
"The momentum of objects depends upon how much volume they occupy" is FALSE.
<u>Explanation:</u>
The quantity of movement by a body is estimated as a function of its mass and velocity.The quantity of momentum an object can have it depends on two variables i.e how much mass moves and how quickly the mass moves. In simple it is dependent on mass and velocity.
There is a difference between mass and volume, as mass is the quantity of matter an object contains while volume is space occupied by mass. For an instance, the bowling ball have more momentum than a basketball, because bowling ball have much more mass and velocity than basketball, although both type of ball have approximately same volume.
