What is the Kinetic Energy of a 60 kg person on skis traveling 20 m/s? (KE = ½ mv2)

Remember ENERGY is measured in JOULES!24,000 Joules

1,200 Joules

12,000 Joules

600 Joules

Explanation:

equating the parameters into the formula, it's gonna be

= ½ × 60 × 20²

= ½ × 60 × 400

= ½ × 24000

K.E = 12000J

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
