How far will 350 J raise a 7Kg mass?

To find out how far 350 J will raise a 7 kg mass, we can use the formula for gravitational potential energy, which is ( PE = mgh ), where ( PE ) is the potential energy (in joules), ( m ) is the mass (in kilograms), ( g ) is the acceleration due to gravity (approximately ( 9.81 , \text{m/s}^2 )), and ( h ) is the height (in meters). Rearranging the formula to solve for height gives us ( h = \frac{PE}{mg} ). Substituting in the values, we get ( h = \frac{350 , \text{J}}{7 , \text{kg} \times 9.81 , \text{m/s}^2} \approx 5.1 , \text{m} ). Thus, 350 J can raise a 7 kg mass approximately 5.1 meters.
