Answer:

10\pi sec

Step-by-step explanation:

distance travelled in 1 rotation = 2\pi rad

d in 10 rotations = 20 \pi rad

we know speed = distance/ time

⇒ 2 = 20\pi/ time

⇒ time = 10 \pi sec

Answer:

It takes 10π seconds to make 10 rotations.

Step-by-step explanation:

A wheel is spinning at 2 radians in keeping with second.

We should calculate 10 rotations in seconds.

1 rotation makes 2π radians.

Distance travelled in 1 second = 2 radians

So, time taken to complete 10 rotations = 10 × 2π = 20π radians

                                                                                = \frac{(20\pi) }{2} seconds

                                                                                = 10π seconds.

Therefore, It takes 10π seconds to make 10 rotations.
