If a skier travels at a constant velocity downhill, this means the forces on her are: ................. A. Zero B. Negligible C.
Vlad1618 [11]

Answer:

F = 0

Explanation:

The net force acting on an object is given by the product of mass and acceleration. We know that acceleration is equal to the rate of change of velocity.

Net force,

F = ma

F=\dfrac{m(v-u)}{t}

The skier is traveling at a constant velocity, it means there is no change in velocity i.e. acceleration is equal to 0. Hence, the force on her is 0.

How much force is required to move a sled 5 meters if a person uses 60 J of work?
Brut [27]
W=F*S

W - Work
F - Force
S - Distance (from latin word 'spatium)

so...
S= 5 (m)
W=60 (J)

W=F*S
F=W/S
F=60/5=12 J/m = 12 N (Newtons)
