Question

1. a fancy new roller coaster sits at the top of a 100 - meter drop. the coaster combined with the 6 passengers has a total mass of 4,500kg. what is the potential energy as the roller coaster sits at the top of the drop? m = __ g = h = pe = __

Explanation:

Step1: Identify the formula

The formula for gravitational - potential energy is $PE = mgh$, where $m$ is the mass, $g$ is the acceleration due to gravity ($g = 9.8\ m/s^{2}$ on Earth), and $h$ is the height.

Step2: Identify the values

Given that $m = 4500\ kg$, $h=100\ m$, and $g = 9.8\ m/s^{2}$.

Step3: Substitute the values into the formula

$PE=mgh=4500\times9.8\times100$.

Step4: Calculate the result

$PE = 4500\times9.8\times100=4410000\ J$.

Answer:

$4410000\ J$
