Answer:
The equation of motion is
Explanation:
Lets calculate
The weight attached to the spring is 24 pounds
Acceleration due to gravity is
Assume x , is spring stretched length is ,4 inches
Converting the length inches into feet
The weight (W=mg) is balanced by restoring force ks at equilibrium position
mg=kx
⇒
The spring constant ,
= 72
If the mass is displaced from its equilibrium position by an amount x, then the differential equation is
Auxiliary equation is,
=
Thus , the solution is
The mass is released from the rest x'(0) = 0
=0
Therefore ,
Since , the mass is released from the rest from 4 inches
inches
feet
feet
Therefore , the equation of motion is
The formula of net Force is:
F = ma
where m is the mass of the object
a is the acceleration of the object
so if we triple the net force applied to the object:
3F = ma
a = 3F / m
so the acceleration will also be tripled. because from the equation, the force is directly proportional to the acceleration
