Question

In the screen shot all I need is number 6

Answer 1

Given that the mass of the car is m = 50 g

The height of the hill is h = 75 cm

A) We have to find the mass of the car in kg.

The mass of car in kg is

`\begin{gathered} m=(50)/(1000) \\ =0.05kg \end{gathered}`

B) The height of the hill is

`\begin{gathered} h=\text{ }(75)/(100) \\ =0.75m\text{ } \end{gathered}`

The acceleration due to gravity is g = 9.8 m/s^2

C) Potential energy will be

`\begin{gathered} U=\text{ mgh} \\ =0.05*9.8*0.75 \\ =0.3675\text{ }J \end{gathered}`
