I would say B. Because actual mass would ricochet off the sidewalk.
Answer:
final velocity will be44.72m/s
Explanation:
HEIGHT=h=100m
vi=0m/s
vf=?
g=10m/s²
by using third equation of motion for bodies under gravity
2gh=(vf)²-(vi)²
evaluating the formula
2(10m/s²)(100m)=vf²-(0m/s)²
2000m²/s²=vf²
√2000m²/s²=√vf²
44.72m/s=vf
Mass is the amount of matter in a material while weight is a measure of how the force of gravity acts upon the mass.
I think the answer is false
I think phosphorus has the highest density at room temp.
