Explanation:
The given data is as follows.
mass (m) = 0.160 kg, spring constant (k) = 8 n/m,
Maximum speed (
) = 0.350 m/s
Formula for angular frequency is as follows.


= 7.07 rad/sec
(a) Formula to calculate the amplitude is as follows.

A = 
= 
= 0.05 m
Hence, value of amplitude is 0.05 m.
(b) Displacement = 0.030 m
Formula for mechanical energy is as follows.
M.E = 
Putting the values into the above formula as follows.
M.E = 
= 
=
Joule
For x = 0.03,
As, P.E = 
= 
= 
Hence, calculate the kinetic energy as follows.
K.E = M.E - P.E
= (
-
) J
=
J
Thus, we can conclude that kinetic energy of the puck when the displacement of the glider is 0.0300 m is
J.
The following that describes how outer space, air, and
glass affect the speed of light is that light travels fastest through outer space, it travels somewhat slower though
air, and of these three, it travels the slowest through glass. The answer is
letter B.
Velocity of an object is given as

now we have

time = 3 hours
now from above formula


so its velocity is 40 mph and its a vector quantity whose direction is towards NORTH
correct answer is B
