Achild generates 42 w of power as she pulls a wagon forward across a flat sidewalk with a force of 70 n. the child pulls with this force for 4.5 minutes. what distance does the wagon move?

110 m

160 m

75 m

210 m

160 m

Explanation:

Power = energy / time

Energy = force × distance

Substituting:

Power = force × distance / time

42 W = 70 N × d / (4.5×60 s)

d = 162 m

Rounded to two significant figures, the distance is 160 m.

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048
