A machinist is using a wrench to loosen a nut. The wrench is 25.0 cm long, and he exerts a 17.0-N force at the end of the handle at 37° with the handle (see Figure) What torque does the machinist exert about the center of the nut?1)The rotor on a helicopter turns at an angular velocity of 3.2x102 revolutions per minute. Express this angular velocity in radians per second.2)The rotor on a helicopter turns at an angular velocity of 3.2x102 revolutions per minute. If the rotor has a radius of 2.00 m, what arclength does the tip of the blade trace out in 3.00x102 s?A turntable rotates with a constant angular acceleration. After 4.00 s it has rotated through an angle of 60.0 rad. What was the angular velocity of the wheel at the beginning of the 4.00-second interval?
