Question

1. a runaway wagon rolls down a hill. it has 37 j of kinetic energy and 84 j of total mechanical energy. how much potential energy does the car have? $pe = me - ke$ 3108 j 121 j 47 j 2.27 j clear all

Explanation:

Step1: Identify given values

ME = 84 J, KE = 37 J, formula: \( PE = ME - KE \)

Step2: Substitute values into formula

\( PE = 84 - 37 \)

Step3: Calculate the result

\( 84 - 37 = 47 \)

Answer:

47 J (corresponding to the option "47 J")
