Question

A 46.0 g golf ball is travelling with a velocity of 5.10 m/s. What is the kinetic energy of the golf ball

Answers

  1. Answer:

    0.598\:\mathrm{J}}

    Explanation:

    The kinetic energy of a golf ball is given by KE=\frac{1}{2}mv^2.

    Since the golf ball is given in grams, we must convert to kilograms, as the SI unit of mass is kilograms.

    46.0\:\mathrm{g}=0.046\:\mathrm{kg}

    Substituting given values, we have:

    KE=\frac{1}{2}\cdot 0.046\cdot 5.10^2=\boxed{0.598\:\mathrm{J}}
