Question

What is the kinetic energy of a car with a mass of 1,532 kg if it’s traveling at 10.6m/s? Submit your answer in exponential form.

Answer 1

In order to determine the kinetic energy of the car, use the following formula:

`K=(1)/(2)mv^2`

where,

m: mass of the car = 1,532kg

v: speed of the car = 10.6 m/s

Replace the previous parameters into the formula for K and simplify:

`\begin{gathered} K=(1)/(2)(1532kg)(10.6(m)/(s))^2 \\ K=86067.76J\approx8.6\cdot10^4J \end{gathered}`

Hence, the kinetic energy of the car is approximately 8.6*10^4J
