<span>1g=32 ft per second ^2
62.6=330528ft
62.6 miles per hour =330528ft perhour=(330528ft perhour/3600seconds per hour)=91.8ft per second
formula for the velocity (v(t))in feet per second at time t in seconds :
v(t))=224t+v0,v0=initial velocity = 0ft per seconds
v(t))=224t
224t =91.8
t=0.409seconds</span>
No but why do you want to know this
The frictional force acts upwards, so as to oppose the downward force of gravity. The reason that pressing against the wall harder makes the book stick more is because the reaction force from the wall increases and frictional force is directly proportional to reaction force.
Electromagnetic waves<span> differ from mechanical </span>waves<span> in that they </span>do<span> not require a </span>medium<span> to propagate. This means that electromagnetic </span>waves<span> can </span>travel<span> not only </span>through<span> air and solid materials, but also </span>through<span> the vacuum of space.</span>
