A car accelerates uniformly in a straight line
Alinara [238K]

Recall that

{v_f}^2={v_i}^2=2a\Delta x

The car starts from rest, so v_i=0, and we get

{v_f}^2=2\left(2.8\dfrac{\rm m}{\mathrm s^2}\right)(69\,\mathrm m)\implies v_f\approx19.66\dfrac{\rm m}{\rm s}

A 13 kg rock is sitting on a cliff. If the rock has 3,500 joules of potential energy, what is the height of the cliff in meters?
Bezzdna [24]

<u>Answer:</u>

The height of the cliff in meters = 27.44

<u>Explanation:</u>

 The potential energy of a body is given by the expression, PE = mgh, where m is the mass of the body, g is the acceleration due to gravity value and h is the height of the body.

 Here we have mass of rock = 13 kg

                          Potential energy = 3500 J

                          Acceleration due to gravity  = 9.81m/s^2

                          Substituting   3500 = 13 * 9.81 * h

                                                       h = 27.44 meter

      The height of the cliff in meters = 27.44
