A gadget to dry lettuce leaves consists of a small perforated cylinder container mounted inside a larger cylinder container so that the small cylinder can be rotated about its axis by turning a hand crank. Wet leaves are placed in the small cylinder and spun to remove
water. If the radius of the small cylinder is 12.0 cm and rotates at 3.0 revolutions per second, determine the magnitude of the linear
speed of the water in the unit of m/s, as the water leaves the wall of the small cylindrical container. Provide an answer to one decimal
place, do not include units.
Answer

Learning goal: to understand newton's 1st law. newton's principia states this first law of motion: an object subject to no net force maintains its state of motion, either at rest or at constant speed in a right line. this law may be restated as follows: if the sum of all forces acting on an object is zero, then the acceleration of that object is zero. mathematically this is just a special case of the 2nd law of motion, f⃗ =ma⃗ , when f⃗ =0. when studying newtonian mechanics, it is best to remember the 1st law in two ways: if the net force (i.e., sum of all forces) acting on an object is zero, the object will keep moving with constant velocity (which may be zero). if an object is moving with constant velocity, that is, with zero acceleration, then the net force acting on that object must be zero. complete the following sentences to see if you can apply these ideas. part a if a car is moving to the left with constant velocity, one can conclude that
