Do Now Draw the following problem and answer it. Now this 4 kg block on a pulley, which is being pulled with a force of 20 N to the right, experiences 4 N of friction. Draw the forces acting on the block, on the diagram above. What is the net force this block is experiencing? What is the acceleration of this block? If the block’s initial velocity is 0 m/s, what is the block’s final velocity after 4 seconds?

TORQUE

You are using a wrench to tighten a bolt. You know that you need a Torque of 20 Nm to tighten the bolt completely. You also know that you can apply a maximum force of 100 Newtons. How far away from the head of the wrench, must you hold the wrench to apply the torque you need?
