10000 n of force is used to accelerate a 400-kg football sled. what is the acceleration of the sled?

Newton's 2nd law of motion says . . . Force = (mass) · (acceleration)

If we divide each side by (mass), it says ... Acceleration = Force/mass

That's exactly what we need.

Acceleration = (10,000 Newton) / (400 kg)

Acceleration = (10,000 / 400) (Newton/kg)

Acceleration = 25 m/s²  (almost 2.6 Gs)

thermal energy is the answer

dang that balls went far
