Answer:
How much force is required to cause an object with a mass of 850 kg to accelerate at a rate of 2 meters per second squared (m/s^2)?
Explanation:
<em>1700N
</em>
<em>
Mass multiplied by acceleration gives you the amount of force needed for it.</em>
T = 3.5 secs
Velocity (v) = g * t = 10 m/s^2 * 3.5 sec = 35 m/s
Answer:
C
Explanation:
they both have to be the same for both to not move
