3. A student wants to find the speed of the ball after colliding with the can. The student says the following: "I know the speed is the slope, so I will do change in position over change in time, My first data point is (0 sec, 0 cm) and my last data point is (0.004 sec. 76 cm]. So speed = (76 -0cm)/(0.004 - Osec) = 19000em/s This is equivalent to 190 m/5." What was the error in the student's reasoning? Explain how to fix their mistake
