Instantaneous Velocity v = ∆d t Sep 1515:06 Sep 1515:12 Motion of Freely Falling Bodies d = 0 m d = 4.9 m d = 19.6 m d = 44.1 m d = 78.4 m d = 122.5 m t = 3.0 s d = ? g = 10 m/s2 vo = ? s displacement (units: m) v final velocity (units: m s¹) u initial velocity (units: m s¹) t time duration (units: s) a acceleration (m s2) All objects in free fall experience the same force of gravity but do all ojects fall with an acceleration 0f 9.8 m/s2? Oct 129:50 AM Oct 1210:10 AM An airplane accelerates down a runway at 3.20 m/s2 for 32.8 s until is finally lifts off the ground. Determine the distance traveled before takeoff. Homework Page 8285 # 4, 8, 9, 32, 33 A race car accelerates uniformly from 18.5 m/s to 46.1 m/s in 2.47 seconds. Determine the acceleration of the car and the distance traveled. A feather is dropped on the moon from a height of 1.40 meters. The acceleration of gravity on the moon is 1.67 m/s2. Determine the time for the feather to fall to the surface of the moon. With what speed must an object be thrown to reach a height of 91.5 m (equivalent to one football field)? Assume negligible air resistance.
