F = (mass)(acceleration) = ma
m = 0.2 kg
Vi = 32 m/s
t = 0.5 s
Vf = 0 m/s (since it was put to stop)
a=(Vf-Vi)/t
a=(0-32)/0.5
a = 64 m/s^2 (decelerating)
F = ma = (0.2 kg)(64 m/s^2)
F = 12.8 N

Answer:
Because the soundwave bounces back when it hits the wall. Only a fraction of the soundwave gets transferred through the wall.
TRUE
They propagate perpendicular to each other in the case of an Electromagnetic waves....
Both can be seen in the case of a moving charge
Hope this helps!
