Answer: Addition polymerization & Condensation polymerization
Answer:
5m/s/s
Explanation:
force = mass x acceleration
50 = 10a
a=5m/s/s
Y - yo = Vo*t - g * (t^2) / 2
Vo = - 9.0 m/s
t = 0.50 s
=> y - yo = -9.0 m/s * 0.5 s - 9.8 m/s^2 * (0.5s)^2 / 2 = - 4.5m - 1.225m = - 5.725 m.
Answer: option c) - 5.7
