1. The problem statement, all variables and given/known data Calculate the impulse(change in momentum) in each of the following situations. Also, state the direction of the change in momentum. A 4kg ball strikes a stationary pin head-on at a speed of 3m/s. It continues to move in its original direction, but its speed is reduced to 2m/s. 2. Relevant equations p=mv 3. The attempt at a solution I have a test the next day & we might have some questions on impulse but the thing is that our teacher never really spent time on it for some odd reason. But yeah, just in case he might troll us & put some impulse questions I might as well do some. So all I got so far is: p1=mv1 p1=3x4 p1=12 ========================== p2=mv2 p2=4x2 p2=8 ============================== (delta)p=p2-p1 =8-12 (delta)p=4 =================== not sure what to do next after..
