Choose the correct word to make a sensible statement.
The first law of motion is the law of
inertia
+ . It means that an
object will remain
+ at rest or
will change
* in motion unless
an external force
* will act
on it.
The second law of
+ is
law of
+ it states that
with an increasing mass of an object, requires
* force to maintain the
The
* law is the law of
+ . It means that when
the Ist object exerts force unto 2nd object, the second
object exerts
+ amount
of force but in

Sitting in a chair connected to a rope that passes over a frictionless pulley (see Figure), Nick pulls on the loose end of the rope with such a force that the spring scale reads 250 N. Nick's true weight is 320 N, and the chair weighs 160 N. Nick's feet are not touching the ground. (a) Draw one pair of diagrams showing the forces for Nick and the chair considered as separate systems and another diagram for Nick and the chair considered as one system. (b) Show that the acceleration of the system is upward and find its magnitude. (c) Find the force Nick exerts on the chair. 2.arrow_forwardMoments after making the dreaded decision to jump out the door of the airplane flying at 11,938 feet, a skydiver's 80.7-kg body experiences 119 N of air resistance.
