Using conservation of energy, find the speed vb of the block at the bottom of the ramp. express your answer in terms of some or all the variables m, v, and h and any appropriate constants.

√(v² + 2gh)

Explanation:

PE₀ + KE₀ = PEƒ + KEƒ

At the top of the ramp, potential energy will be at a peak and kinetic energy will be at a least. At the bottom of the ramp, kinetic energy will be at a peak and potential energy will be least . Although the type of energy changes, the total amount of energy remains the same. Meaning energy can neither be created nor destroyed, but can be transformed from one point to another.

mgh + ½mv² = mgh(b) + ½mv(b)²

Since the height at the bottom is zero, potential energy can be removed from the right side of the formula:

mgh + ½mv² = ½mv(b)²

gh + ½v² = ½v(b)²

2gh + v² = v(b)²

v(b) = √(v² + 2gh)

= √(v² + 2gh)

i know this is true mom has it.

mark me branliest only got it 1 time!

science is a systematic and logical approach to discovering how things in the universe work. true to this definition, science aims for measurable results through testing and analysis. science is based on fact, not opinion or preferences. the process of science is designed to challenge ideas through research.
