Explanation:
inertia is the ability of a body to remain at rest or in a constant speed in a constant direction when no force is acting on it
Work=force X distance
Newtons is a measurement of force
4 meters is your distance 60×4=240
240 joules
<h2>Book will hit the foot with force 21.8 N</h2>
Explanation:
The momentum of any object = m v
here m is the mass of body and v is its velocity
Thus momentum P = 3.2 x 1 = 3.2 kg-m
As the book is falling freely , so it will fall with and acceleration g
The force exerted by it is = m g
Thus force = 2.18 x 10 = 21.8 N
