Answer:
a) Revolutions per minute = 2.33
b) Centripetal acceleration = 11649.44 m/s²
Explanation:
a) Angular velocity is the ratio of linear velocity and radius.
Here linear velocity = 72 m/s
Radius, r = 0.89 x 0. 5 = 0.445 m
Angular velocity
Frequency
Revolutions per minute = 2.33
b) Centripetal acceleration
Here linear velocity = 72 m/s
Radius, r = 0.445 m
Substituting
Centripetal acceleration = 11649.44m/s²
The Kinetic energy of an object is given by:
Where m is the mass of the object (kg) and v is the velocity of the object (ms-1)
Substituting in:
Therefore the Kinetic energy of the object is 1.35MJ
Where m is the mass of the object (kg) and v is the velocity of the object (ms-1)
Substituting in:
Therefore the Kinetic energy of the object is 1.35MJ
