Question

determine the kinetic energy of a roller coaster car has a mass of 740 kg and zips by you at 33.5 m/s

Answer 1

The kinetic energy of the car is $4.15\cdot 10^5 J$

Explanation:

The kinetic energy of an object is the energy possessed by the object due to its motion.

Mathematically, the kinetic energy is

$K=\frac{1}{2}mv^2$

where

m is the mass of the object

v is its speed

For the car in this problem,

m = 740 kg

v = 33.5 m/s

Therefore, the kinetic energy of the car is

$K=\frac{1}{2}(740)(33.5)^2=4.15\cdot 10^5 J$
