The velocity of a falling object can be determined with the formula V=2gh where g = the acceleration due to gravity (9.81 m/s2) and h = the height the ball was dropped from (in this case, 1 m.) Notice the velocity will be the same for each ball regardless of what they are made of or what surface they were bounced on. Calculate this velocity here (show your work, don’t forget units): can someone explain this as dull as possible

Figure 9 on page 362 shows various motions of balls. the curved path followed by the yellow ball in b in picture b is result of a) inertia b) centripetal motion c) gravity and horizontal velocity d) linear motion
