Question

in another attempt, bala used another ramp that ends at point m as shown below. (b) explain, in terms of energy conversion, if bala will succeed in jumping over the barrier. 2

Explanation:

At the start, Bala has potential energy (due to height) and kinetic energy (if moving). As he moves down the ramp, potential energy converts to kinetic energy. As he moves up towards point M, kinetic energy converts back to potential energy. For Bala to jump over the barrier, he must have enough kinetic energy at the start (or convert enough potential - kinetic - potential energy) such that his potential energy at point M is greater than the potential energy required to clear the barrier's height. If friction and air - resistance are negligible and his initial energy is sufficient for the height gain to clear the barrier, he can succeed. If energy is lost to non - conservative forces (friction, air - resistance), he may not have enough energy to clear the barrier.

Answer:

It depends on initial energy and energy losses. If initial energy is sufficient and energy losses to non - conservative forces (friction, air - resistance) are small, he can succeed; otherwise, he may not.
