Question

a body rotates at 300 rotations per minute. The value in Radian of the angle described in one second is

Answer 1

Answer: The angle is $10\pi radian$.

Explanation:

Given that,

Number of revolution in one minute = 300

So, number of revolution in one sec = $\dfrac{300}{60}=5$

We know that,

Angle rotated in one revolution = $2\pi$

So, angle rotated in 5 revolution = $5\times2\pi=10\pi radian$

Hence, the angle is $10\pi radian$.

Answer 2

"Number of revolution in one minute = 300

So, number of revolution in one sec $=\frac{300}{60} = 5$

We know that,

Angle rotated in one revolution $= 2\pi$

So, angle rotated in 5 revolution $= 5 \times 2\pi = 10 \pi$

Hence, the angle is $10\pi radian.$

Rotation motion is a "type of motion" in which the object is fixed at the centre and it moves around its axis. The revolution of the object depends on its speed and the distance of rotation."
