How do you find final kinetic energy?
Kinetic energy from what? What variables are given?
Ma= 1750 kg
Va= 30 m/s
Vb=0 m/s
Mb=2000 kg
Vf=14 m/s
Pf=52500 kg m/s
Pa= 52500 kg m/s
Pb= 0 kg m/s
Ka= 787500 J
Kb= 0 J
KE = 1/2 mv^2
You already know the final mass and the final velocity
final mass (Ma+Mb)
final velocity= 14 m/s
im assuming this is a continuation of the other posted question
To find the final kinetic energy of an object, you need to know its mass and velocity. The formula to calculate the kinetic energy is:
Kinetic Energy (KE) = 1/2 * mass * velocity^2
So, to find the final kinetic energy, follow these steps:
1. Determine the mass of the object in kilograms (kg).
2. Measure or calculate the velocity of the object in meters per second (m/s).
3. Square the velocity by multiplying it by itself.
4. Multiply the squared velocity by half of the mass.
5. The result will be the final kinetic energy of the object, expressed in joules (J).
Remember to use consistent units for mass and velocity in order to obtain accurate results.
