Given:
mass = 70kg
velocity = 10 m/s
Determine the Kinetic Energy.
Formula for Kinetic Energy:
KE = ½ mv^2
KE= Kinetic Energy
m = mass
v = velocity
Solution:
Substitute the given values of m and v to the formula for the kinetic energy.
KE = ½ (70 kg)(10m/s)^2
KE = ½ (70 kg)(100 m^2/s^2)
KE = ½ (7000 kg. m^2/s^2)
KE = 3500 kg. m^2 /s^2 or J
Final answer:
KE = 3500 J
