A1.47-newton baseball is dropped from a height of 10.0 meters and falls through the air to the ground. the kinetic energy of the ball is 12.0 joules the instant before the ball strikes the ground. the maximum amount of mechanical energy converted to internal energy during the fall

ΔEinternal = - 2.7 J

Explanation:

Given

W = m*g = 1.47 N

hinitial = 10.0 m

Kfinal = 12.0 J

We can apply

ΔE = ΔEinternal

then

ΔE = (Kfinal + Ufinal) - (Kinitial + Uinitial)

⇒   ΔE = (Kfinal + 0 J) - (0 J + Uinitial) = Kfinal - Uinitial

⇒   ΔE = Kfinal - (W*hfinal) = 12 J  - (1.47 N*10.0 m)

⇒   ΔE = 12 J - 14.7 J = - 2.7 J

then

ΔEinternal = - 2.7 J

the answer to this question is 60 n

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.
