What is the kinetic energy of an automobile with a mass of 1250 kg traveling at a speed of 11 m/s?
(.5)(1250)(11)^2=75625
To calculate the kinetic energy of an object, you need to use the following formula:
Kinetic Energy = 1/2 * mass * velocity^2
Given:
Mass (m) = 1250 kg
Velocity (v) = 11 m/s
To find the kinetic energy, substitute the values into the formula and solve:
Kinetic Energy = 1/2 * 1250 kg * (11 m/s)^2
First, square the velocity:
Kinetic Energy = 1/2 * 1250 kg * (121 m^2/s^2)
Next, multiply the squared velocity by the mass:
Kinetic Energy = 1/2 * 1250 kg * 121 m^2/s^2
Now, multiply the mass by the squared velocity:
Kinetic Energy = 1/2 * 151250 kg m^2/s^2
Finally, simplify the expression:
Kinetic Energy = 75625 kg m^2/s^2
Therefore, the kinetic energy of the automobile is 75625 kg m^2/s^2.
KE=.5m(v)^2
so we have 1250 times 121 then divide by 2.
the formula reads kinetic energy equals mass times velocity squared then divided by 2
