Looks fun, have you tried anything or noticed anything "interesting" of figure b?

Answer 3

what is the question for this exercise ?

Answer 4

You should use the concept of 'impulse' and momentum to solve this.

The Impluse is the area under the F-t graph

You can see from the graph that his is HALF the area of the enclosing rectangle

Total implse = change of MOMENTUM (mv)

You know the impulse, you know the mass so you can work out the CHANGE of velocity.

Add the initial velocity (2 m/s) to get the answer
