The car has a mass of 1200kg
Calculate the kinetic of the car when it travels at a speed of 12 m/s.
Compute (1/2) M V^2
using M = 1200 and V = 12.
The answer will be in joules.
Use the formula 1/2*m*(v^2) where m=1200 kg, and v=12 m/s.
Substitute, and you get .5*1200*(12)^2=86400 J
To calculate the kinetic energy of an object, you can use the formula:
Kinetic Energy (KE) = 1/2 * mass * velocity^2
Given:
Mass of the car (m) = 1200 kg
Speed of the car (v) = 12 m/s
Plugging the values into the formula:
KE = 1/2 * 1200 kg * (12 m/s)^2
First, square the value of the speed:
KE = 1/2 * 1200 kg * (144 m^2/s^2)
Next, multiply the squared speed by the mass:
KE = 1/2 * 1200 kg * 144 m^2/s^2
Next, multiply the mass by the squared speed:
KE = 1/2 * 1200 kg * 144 m^2/s^2
KE = 1/2 * 172800 kg * m^2/s^2
Finally, calculate the answer:
KE = 86400 kg * m^2/s^2
Therefore, the kinetic energy of the car traveling at a speed of 12 m/s is 86400 kg * m^2/s^2.
