Answer:
A) Increases by a factor of 2
Explanation:
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
Where;
K.E represents kinetic energy measured in Joules.
M represents mass measured in kilograms.
V represents velocity measured in metres per seconds square.
Given that mass, m = 2m
Substituting into the equation, we have;
K.E = ½mv²
K.E = ½*2mv²
Cross-multiplying, we have;
2K.E = 2mv²
Hence, if the mass of an object increases by a factor 2, kinetic energy is increased by a factor of 2.
If we start taking into account the free body diagram, we then start damping motion of a body by means of this equation:
<span>m * d^2 x/dt^2 + c* dx/dt + k* x = 0 </span>
<span>free undamped motion is when (c =0) </span>
<span>therefore </span>
<span>50* d^2 x/dt^2 + 200* x = 0 </span>
<span>w = omega = sqrt(k/m) = sqrt(200/50) = 2 </span>
<span>Then </span>
<span>A*cos(w*t) + B*sin(w*t) = x </span>
<span>find A and B using intial conditions and you will get the rest that you need. Hope this helps</span>
