1. Newton's Second Law indicated that when a net force acts on an object, it must accelerate. Does this mean that when two or more forces are applied to an object simultaneously, it must accelerate?
2. An airplane has a mass of 3*10^4 kg and takes off under the influence of a constant net force of 35 000 N. What is the net force that acts on the plane's 80-kg pilot, assuming that he has the same acceleration as the plane?
3. Derive equation in the Lab Manual.
g = aave (M+m)/m
T1 - f = M *a1
mg - T1 = m* a1
T2 + f = M *a2
m g - T2 = m a2
aave = (slope 1 + slope 2)/2
