PoU: Impulse to Determine Forces
1. You are required to use the impulse equation to find the net force applied by the stick to the puck. What specific data will you
need to gather and how will you gather it?
Hint: Format your answer like the example below.
delta t time of contact between the puck and stick. Use the stopwatch.
Also 169.7 g = 0.1697 kg

2. Determine the net force applied by the stick on the puck. Show all calculations.
BIU

The answer is a 0.64 volts

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
