solution:
the spring force exerted by spring with spring constant k is given by
where k is spring constant
and x is deformation of spring
in order to calculate word done by the spring
the work done by the spring as it is compressed from x=0 to x=L
inserting the limits x=0 and x=L
we get work done in terms of k and L
Answer:
6.746 ft/s^2
Explanation:
v(t)=50
v(0)=27
t=5/3600 = 1/720 hours
v(t)-v(0)= a(t-0)
50-27= a(1/720)
a= 23*720= 16560 mi/h^2
16560mi/h^2 * 5280/3600^2 (ft/s^2) =6.746 ft/s^2
<h2>Answer : </h2>
20cm spanner is suitable to open this nut , Because we feel easy to apply force at the end of spanner to rusted nut. It means that as the perpendicular distance between force and axis of rotation increase the magnitude of moment also increase.
I think the Answer will helps you.....
Thank you ☺️☺️☺️
