What is the kinetic energy of a go kart with a mass of 150 kilograms and a speed of 20 m/s?

Kinetic Energy = 1/2mv^2

Kinetic Energy = 1/2(150 kg)(20 m/s)^2

Kinetic Energy = 75 kg(400 m/s)

Kinetic Energy = 30000 J

Let me know if this helps!

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
