Answer:

Explanation:

Only force in the direction of motion does work

The force acts in the x direction

The x change of position was 6 m

W = Fd = 12(6) = 72 J

A 4.4 kg marble (really big heavy marble) is accelerating down an incline. When it reaches level ground it slows down to a stop
KengaRu [80]

#A

Mass=4.4kg

acceleration=-1.74m/s^2

Use newtons second law

\\ \rm\longmapsto Force=ma

\\ \rm\longmapsto Force=4.4(-1.74)

\\ \rm\longmapsto Force=-7.656N

#B

initial velocity=u

Final velocity=v=0

Acceleration=a=-1.74m/s^2

Time=t=1.27s

\\ \rm\longmapsto a=\dfrac{v-u}{t}

\\ \rm\longmapsto u=v-at

\\ \rm\longmapsto u=0-(-1.74)(1.27)

\\ \rm\longmapsto u=1.74(1.27)

\\ \rm\longmapsto u=2.2m/s

Ivan exerts 20 N of force to lift a basket 2 m. He then carries the basket 5 m across a room to place it on a shelf. Ivan does w
amid [387]
A) <span>Ivan does work when he lifts the basket

B) Work = Force * displacement 
W = 20 * 2
W = 40 Joules

So, The Amount of work he does is 40 Joules

Hope this helps!</span>
