The force vs. time graphs for two collisions are shown. Which collision has the largest impulse?

The impulses are the same.
The impulse for collision 2 since it lasts longer.
The impulse for collision 1 since it has the larger maximum force.
Cannot be determined since the initial an final speeds are unknown.
Cannot be determined since the masses are unknown.

Expert Solution

The impulse is the area under the graph.
so collision one is .5*4=2
collision two is 1*2=2

So the answer is A; they are the same.

The same cart again traveling at 0.3 m/s collides with a different stationary object. This time the cart is at rest after the collision. In which collision is the impulse on the cart greater?

A cart traveling at 0.3 m/s collides with stationary object. After the collision, the cart rebounds in the opposite direction. The same cart again traveling at 0.3 m/s collides with a different stationary object. This time the cart is at rest after the collision. In which collision is the impulse on the cart greater? A. The impulses are the same. B. The second collision. C. The first collision. D. Cannot be determined without knowing the mass of the cart. E....
