The figure on the right shows the graph of the force exerted by a hockey stick on a puck. If the puck has a mass of 150 g, what is the speed of the puck after it leaves the stick?
A) 20 m/s B) 3.0 m/s C) 6.0 m/s D) 45 m/s

I can’t get the figure up, but the figure is a Force x Time graph in the shape of a triangle. The base of the triangle starts at 0s and ends at 2s. However, the graph peaks at 3 slightly before the 1 second mark.

I figure I need to find out what F(avg) is, so I can find J. But because the triangle is not a perfect triangle, I am unsure if F(avg) is 1.5. (Found that by .5(base)(height)). Any help is very much appreciated. Thankyou!
