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.

Sagot :

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

[tex]K=\frac{1}{2}mv^2[/tex]

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:

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

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