3. Three balls (m, < m2 < m3) are launched near the surface of earth from the same initial distance from the ground h. m1 is launched directly upwards at speed v1, m2 is thrown directly downward at the same speed, and m3 is dropped. Air resistance is very small.* o Calculate the time it takes each ball to reach the ground and the speed they hit the ground in terms of the variables given. Compare these values for the three balls. o If m1=0.056kg, m2=0.625kg, m3=5.4kg, the initial speed for balls 1 and 2 is 10m/s, and the initial height is 50m above the ground, calculate your answers for each ball. In physics problems, this usually means it is a reasonable assumption to neglect air resistance.
