1. The problem statement, all variables and given/known data Bronco Brown wants to put Ft =∆mv to the test and try bungee jumping. Bronco leaps from a high cliff and experiences free fall for 3 seconds. Then the bungee cord begins to stretch, reducing his speed to zero in 2 seconds. Fortunately, the cord stretches to its maximum length just short of the ground below. 2. Relevant equations ∆mv at 3-s free fall is 3000 kg m/s Then the question asks: ∆mv during the 2-s interval of slowing down 3. The attempt at a solution To my knowledge it is at final velocity leaving it at 3000 kg*m/s Would it be 1500kg m/s or 3000kg m/s? I think 3000, but i'm not sure the equation to understand it. The equation I used gave me 1500 because of the slowing down. Please help me understand this better.
