Question
Calculate the kinetic energy of the pole vaulter when they reach their top speed.kinetic energy, Ek = ½mv2
Solution
To calculate the kinetic energy of the pole vaulter when they reach their top speed, you need to know the mass of the pole vaulter (m) and their top speed (v). The formula for kinetic energy (Ek) is ½mv².
Here are the steps:
-
Determine the mass of the pole vaulter in kilograms (kg). Let's say the mass is m kg.
-
Determine the top speed of the pole vaulter in meters per second (m/s). Let's say the top speed is v m/s.
-
Substitute the values of m and v into the formula.
Ek = ½ * m * v²
-
Calculate the result. This will give you the kinetic energy of the pole vaulter at their top speed in joules (J).
Remember, you need to have the mass and speed in the correct units (kg and m/s respectively) for this calculation to be accurate.
