Answer:kinetic energy converted to heat energy
Explanation:
As the ball rolls down kinetic energy is converted to heat energy
Answer:
Explanation:required formula is
W 1=F*S
W1=work done by Sam =?
F=force applied by sam=150N
S=displacement =10m
again
W2=F*S
W2=work done by friction =?
S=displacement =10m
F=friction =25N
W=W1-W2=net work done
please feel free to ask if you have any questions
Its actually C. I did the question on USA test prep and it said the correct answer was C.
