Since they are made of different chemical make ups, boiling point and density they will most likely be in different groups on the periodic table.
Answer:
Explanation:
a) KE = (1/2) * m * (
) = F * d = 14m * 200N = 2800 m/N or 2.8 *
m/N
b) 0J and 0m/s (if Marcella stopped after going 14 meters)
c) Known from part (a) that KE = 2800 J = F1 * d1,
2800J = F1 * (14m - 1m) => F1 = 2800J/13m = 215.384 N
Answer:
80m<em>/</em><em>s</em>
Explanation:
Final velocity is given by
v=u+at
when a motorcyclist starts from rest, initial velocity (u) =0
therefore
v=0+4*20
v=80m/s
that's the answer
