This problem here is an example of inelastic collision where kinetic energy is not conserved but momentum is. We calculate as follows:
m1v1 + m2v2 = (m1 + m2)v3
v3 = m1v1 + m2v2 / m1 + m2
v3 = (30.2)(1000) + (5000)(0) / (30.2 + 5000)
v3 = 6.00 m/s
It grows every time it needs to grow for the population of the environment
Answer:

Answer:
Ws=8.75 Watts
Explanation:
As per fig. of prob 02.061, it is clear that R5 and R4 are in parallel, its equivalent Resistance will be:



Now, this equivalent Req45 is in series with R3, therefore:

This Req345 is in parallel with R2, i.e

Now this gets in series with R1:

Now, the power delivered Ws is:

Acceleration = change in velocity / time
= 40 mi/s / 2s = 20 mi/s/s
