The shaft of a motor rotates at a constant angular speed of 3600 revolution per minute. Angle turned through in 1 sec in radians is:
Correct answer: B. 2 π
- A. π
- B. 2 π
- C. 6 π
- D. 120 π
Explanation
The explanation is given below: To find the angle turned through in 1 second in radians (θ), you can use the formula: θ=2πf Given that the shaft rotates at a constant angular speed of 3600 revolutions per minute, first, convert this to revolutions per second: Revolutions per second = 3600 revolutions/ 60 seconds = 60 revolutions per second Now, plug this value into the formula: θ=2π×60 θ = 120π radians

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
