F = ma
F = (1000 kg)•(5 m/s^2)
F = 5000 N
Answer:
Sound energy (that is, mechanical vibrational waves passing through an elastic medium) is a combination of kinetic and potential energies. As the wave compresses the medium (storing elastic potential energy) the medium comes to rest (no motion so no kinetic energy).

Answer:
D1 = 3.50 m, south; D2 = 8.20 m, northeast; D3 = 15.0 m, west. Converting all these displacements from east where zero degrees is at east or + x-axis, the converted displacements are: D1 = 3.50 m 270°; D2 = 8.20 m 45° and D3 = 15.0 m 180°. We then tabulate these vectors including there x and y components. The x-components are solved by magnitudes * cos of direction angle while the y-components of the three vectors are solved by magnitudes * sin of direction angle.
The resultant is computed by summing the components algebraically. The direction in degrees is the arc tangent of the sum of all y divided by the sum of all x.

Explanation:
Change in momentum = m ( v -u )
= .53 ( 18+13.5 )
= 16.7 kg m/s
Impulse = change in momentum
= 16.7 kg m/s
b ) force x time = 16.7
force = 16.7 / .1
= 167 N
force of the wall on the ball
= 167 N.
