An 8 kg cat is running 4 m/s. How much kinetic energy does it have?

Kinetic energy = (1/2) (mass) (speed)²

Kinetic energy = (1/2) (8 kg) (4 m/s)² =

                                 (4 kg) (16 m²/s²) =

                                  64  (kg-m/s²) (m) = 64 newton-m = 64 joules

  (about 17.6 pounds)

Explanation:

c) up is the direction the magnetic force is acting on the charge.

where is the
