<span>The support force is 15 N. The net force on the book is zero.</span>
B. only its velocity should change
Because the scientific method can go around in a circle as many times as neccisary to get the results you need
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
