1. If a person pushed a door with a force of 25 N, and the moment arm was 1m, how much torque is produced? ______Nm 2. During a softball pitch, the pitcher's arm goes through 120 degrees of angular displacement over 0.25 seconds, What is the average angular velocity? _____ degree/s
1) what is the magnitude of the torque exerted by the force F4 on the gate. 2) what is the magnitude of the torque exerted by the force F1 on the gate. 3) what is the magnetude of the torque exerted by the force F2 on the gate. (1,2,3 using the first photo. ) 4) A 4.0 radius grinding stone initially rotates with an angular velocity of 8.0 rad/s. The angular velocity is then increased to 12 rad/s for the...
