Abobsled team accelerates their 150 kg sled at a rate of 3 m/s^2. how much force did they use?

Force used = 450N

Explanation:

Force = Mass × Acceleration

Force = 150kg × 3m/s² = 450Kgm/s² = 450N

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
