12. Rotational Kinematics
Types of Acceleration in Rotation
Multiple Choice
Multiple ChoiceA large disc of radius 10 m initially at rest takes 200 full revolutions to reach 30 RPM. Calculate the total linear acceleration of a point at half way between the disc's center and its edge, once the disc reaches 30 RPM. (You may assume it continues accelerating past that point)
A
15.7 m/s2
B
24.7 m/s2
C
49.3 m/s2
D
98.7 m/s2
13:42m
