how far will 350 j raise a 7 kg mass

Answer 1

And the real School Subject is.....?

Sra

Answer 2

7kg of mass weighs 70N. 350J = 350 Nm^-1.
=> distance moved = (350/70)m = 5m.

Answer 3

correction : 350J = 350Nm (Newton meter)

Answer 4

35

Answer 5

A=F*h => h=F*A => h=A/mg <=> h=350/70= 5 m.

Answer 6

Newton's = Mass * Acceleration
7 * 9.8 = 68.8
Distance = Work / Force
350 / 68.8 = 5.10 m Up
