Question1

Drawing velocity/time graphs of the following motions-

A) a city bus that is moving with a constant velocity

B ) a wheelbarrow that is speeding up at a uniform rate of acceleration while moving in positive direction.

C) A tiger that is speeding up at a uniform rate of acceleration while moving in negative direction.

D) An iguana that is slowing done at a uniform rate of acceleration though moving in positive direction.

E) A camel that is slowing down at a uniform rate of acceleration whereas moving in negative direction.

Question2

A man of mass 81 kg escapes from a burning building by jumping from a window located 30 m above a catching net. The acceleration of gravity is 9.81 m/s2. If air friction exerts a constant force of 88 N on him as he falls, what is the velocity just before he hits the net?
