how far will 350 j raise a 7 kg mass
Newton's = Mass * Acceleration
7 * 9.8 = 68.8
Distance = Work / Force
350 / 68.8 = 5.10 m Up
To calculate how far a certain amount of work (in this case, 350 J) can raise a mass (in this case, 7 kg), you need to use the formula for gravitational potential energy.
Gravitational potential energy (PE) is equal to the product of the mass (m), the acceleration due to gravity (g), and the height (h) it is raised:
PE = m * g * h
You can rearrange this formula to solve for h:
h = PE / (m * g)
Given that the potential energy (PE) is 350 J, the mass (m) is 7 kg, and the acceleration due to gravity (g) is approximately 9.8 m/s², substitute these values into the formula:
h = 350 J / (7 kg * 9.8 m/s²)
Calculating this will give you the height (h) in meters.
7kg of mass weighs 70N. 350J = 350 Nm^-1.
=> distance moved = (350/70)m = 5m.
correction : 350J = 350Nm (Newton meter)
35
A=F*h => h=F*A => h=A/mg <=> h=350/70= 5 m.
And the real School Subject is.....?
