observing collision forces that change with time..
collide the cart with the wall serveral times and observe what happens to the spring pluger
Q1: if friction is negligible,what is the net force exerted on the cart just before it starts to colide?
Q2: when is the magnitude of the force on the cart maximum?
Q3: Rougly how long does the collision process take?Half a second?less time?several seconds?

In this activity you will investigate impulse-momentum for a collision. First consider a foam ball colliding with a wall. When will the magnitude of the force on the ball be a maximum? When the hall first starts to compress? While it is compressing? When it has a maximum compression? Explain. Watch the ball collide with a wall several times. Roughly how long does the collision process take? Half a second? Less? Several seconds? Remembering what you observed, attempt a rough...

refer to picture below.
A force is applied on a cart that is at rest. The force acts for a short time interval and gives the cart a certain final speed. The same force is exerted for an equal length of tim on another cart, also initially at rest, but with twice the mass. The forces of friction are negligible. The final speed of the heavier cart relative to the lighter cart is a. b. one fourth one half the...

Q1 A small object with a momentum of magnitude 2.71 kg m/s approaches head-on a large object at rest. The small object bounces straight back with a momentum of magnitude 6.19 kg m/s. What is the magnitude of the small object's momentum change in kg m/s? Q2 A force acts on a 4.708 kg mass as follows: the force starts at zero and rises to 60.334 N linearly in 2.24 seconds, it remains at 60.334 N for another 5.756 seconds,...

In any question referring to current, conventional current will be used (where conventional current is the flow of positive charges). In addition, all effects due to the earth's magnetic field will be so small that they will be ignored. Note that the term "particle" is meant to be an object without size or structure. 1.
