WebPhysics questions and answers. Starting from rest, approximately how far does an object fall freely in 3 seconds? A. 90m B. 45m C. 30m D. 15m E. 3m As an object thrown upward … WebLet's say the object was thrown up at 29.4 m/s. So since the object was thrown up which a positive direction it is initially traveling at + 29.4 m/s. After 1 second we know that the velocity changed by - 9.8 m/s so at this point in time the object is traveling at a velocity of (+ 29.4 m/s) + (- 9.8 m/s) = + 19.6 m/s.
