Answer:
a)

b)
m = 48lb
c)
b = 144.76lb
Explanation:
The general equation of a damping oscillate motion is given by:
(1)
uo: initial position
m: mass of the block
b: damping coefficient
w: angular frequency
α: initial phase
a. With the information given in the statement you replace the values of the parameters in (1). But first, you calculate the constant b by using the information about the viscous resistance force:

Then, you obtain by replacing in (1):
6in = 0.499 ft

b.
mass, m = 48lb
c.
b = 144.76 lb/s
Answer: C) N: Electrical energy and M: Kinetic energy

Answer:
C. Grass -----> Grasshopper------>Frog
The centre of mass of the objects is (0,1)m .
What do you mean by Centre of mass?
The centre of mass is a position defined relative to an object or system of objects .
We have given
m1=2kg , y1= 3
m2= 3kg ,y2=2.5m
m3=2.5kg ,y3= 0m
m4=4kg , y4= -0.5m
Ycm=mixi/mi
→2×3+3×2.5+2.5×0+4×0.5/4.5
→1m
Centre of mass of these object is at (0,1)m .
