Determine how long it will take an object to rotate through 6.9 revolutions at an angular velocity of 3.1 radians per second. Use. Round the answer to the nearest tenth.

Answer: 13. 99 seconds

Step-by-step explanation:

The formula to find how long it will take an object to rotate through 6.9 revolutions at an angular velocity is given as:

t = 2π x number of revolutions / angular velocity

Therefore:

t = 2π x 6.9 / 3.1

t = 2 x 3.142 x 6.9 / 3.1

t = 43.3596/3.1

t = 13. 98696774194

to the nearest tenth

t = 13. 99s
