How much time does it take a power drill accelerating at 64.3 rad/s2 to achieve

1500. rotations per minute (rpm) ?

Answer;

= 0.244 seconds

Explanation;

500 rpm is equivalent to; 1500 * 2π radians per minute

= 9424.8 rad/minute

To get revolutions per second we divide by 60

= 9424.8/60

= 157.08 radians per second.

Then we divide by 64.3 rad/s^2 to get time;

= 157.08/64.3

= 0.244 seconds.

The time is 0.244 seconds

Explanation:

According to the given data

1500 rpm is 1500 * (2pi) radians per minute = 9424.8 rad/minute

So

Divide by 60 = 157.08 radians per second.

And then

Divide by 64.3 rad/s^2 = 0.244 seconds.
