I would say a because i just had this
F = m . g = 76.5 x 9..8 = 749.7
Net Force = 3225 - 749.7 = 2475.3
F = m.a
2475.3 = 76.5 a
a = 32.35
V = at + v1
V = at + 0
V = 32.35 x 0.15
V = 4.8525
Hope this helps
I'm pretty sure there is only one element named after Mendeleev: <span>Mendelevium.</span>
Sodium (Na) is very reactive because it does not have a full valence shell.
