Question
Download Solution PDFThe initial angular velocity of an object is 10 rad/s. After 10 seconds the angular velocity becomes 20 rad/s. Find the angular acceleration of the object.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is option 1) i.e. 1 rad/s2.
CONCEPT:
- Angular acceleration: It is the rate of change angular velocity of an object with respect to time i.e.
where,α = angular acceleration, ωf = final angular velocity, ωi = initial angular velocity, and t = time
CALCULATION:
Given,
initial angular velocity, ωi = 10 rad/s
final angular velocity, ωf = 20 rad/s
time, t = 10 second
Hence,
angular acceleration, α = (20-10)/10 rad/s2
⇒ α = 1 rad/s2.
