Question

At one point on the Ferris wheel ride, Jessie, who has a mass of 50 kg, has 4,900 joules of GPE. How high is she off the ground?

Please help I’m desperate and don’t understand science math

Answer 1

10 meters

Explanation:

P.E = mgh

4900 = 50 × 9.8 × h

4900 = 490 × h

h = 10 m

Answer 2

We can use the formula for gravitational potential energy (GPE) to find the height at which Jessie is off the ground:

GPE = mgh

where m is the mass of the object (in kg), g is the acceleration due to gravity (9.8 m/s² on Earth), h is the height (in meters) above some reference point where the GPE is defined.

In this case, we know that Jessie has a mass of 50 kg and 4,900 joules of GPE. Plugging these values into the formula, we get:

4900 = (50 kg)(9.8 m/s²)(h)

Solving for h, we get:

h = 4900 J / (50 kg x 9.8 m/s²)

h = 10 meters

Therefore, Jessie is 10 meters off the ground at the point where she has 4,900 joules of GPE.
