Unformatted text preview: (4) acceleration 39. Which graph best represents the motion of an object falling from rest near Earth’s surface? (3) 40. Approximately how far will an object near Earth’s surface fall in 3.0 seconds? (2) 44 m 41. An object starts from rest and falls freely near Earth’s surface for 3.00 seconds. Determine the final speed of the object. V = gt V = (9.81m/s 2 )(3.00s) V = 29.4m/s...
