How many newtons of force are needed to accelerate a 1,875 kg object at a rate of 1.5 m/s2?

 1,950 N

Explanation:

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
