Question

question 11 (1 point) when keeping the sled height the same, as the mass of the sled increased, the speed word bank: decreased stayed the same increased blank 1

Explanation:

Using conservation of mechanical energy (assuming no friction), the potential - energy at the top of the height is converted to kinetic energy at the bottom. The potential energy is $mgh$ and kinetic energy is $\frac{1}{2}mv^{2}$. Setting $mgh=\frac{1}{2}mv^{2}$, the mass $m$ cancels out and $v = \sqrt{2gh}$. So speed depends only on height $h$ and gravitational acceleration $g$, not on mass.

Answer:

stayed the same
