How far will 350 J raise a block weighing 7 kg mass?

Answer 1

To find out how far 350 J of energy will raise a 7 kg block, we can use the formula for gravitational potential energy: ( PE = mgh ), where ( PE ) is potential energy, ( m ) is mass, ( g ) is the acceleration due to gravity (approximately 9.81 m/s²), and ( h ) is the height. Rearranging the formula to solve for height gives us ( h = \frac{PE}{mg} ). Substituting in the values, we have ( h = \frac{350 , \text{J}}{7 , \text{kg} \times 9.81 , \text{m/s}^2} \approx 5.1 , \text{m} ). Therefore, 350 J will raise the block approximately 5.1 meters.
