Question

1. determine the amount of gravitational potential energy for a 3 g acorn in an oak tree that is 17 m tall. 0.5 j 0.05 j 50 j 5 j

Explanation:

Step1: Convert mass to kg

The mass of the acorn $m = 3g=3\times10^{- 3}kg$, the height of the tree $h = 17m$, and the gravitational - acceleration $g = 9.8m/s^{2}$. The formula for gravitational potential energy is $U = mgh$.

Step2: Calculate gravitational potential energy

Substitute the values into the formula: $U=(3\times10^{-3}kg)\times9.8m/s^{2}\times17m$.
$U = 3\times9.8\times17\times10^{-3}J=0.4998J\approx0.5J$.

Answer:

0.5 J
