Answer:

option B

85 J

Explanation:

Given in the question,

mass of the dog = 7.2 kg

height it want to achieve = 1.2m

Formula to use

gravitational energy at maximum height = kinetic energy on the ground level

gravitational energy = mgh

here m = mass

        g = acceleration due to gravity = 9.8 m/s²

        h = height

plug values in the formula

7.2(9.8)(1.2)

84.672 J

≈ 85 J
