A bird accelerates from rest (0 km/hr) to 5.00 km/hr in 2.3 seconds (time). 2 What is its acceleration in m/s? (Note: 1 hr=3600 s, 1000 m =1 km). 21. An airplane must accelerate from rest to about 50 m/s along the runway in order to be able to take off. During the takeoff, the airplane is able to accelerate 4 2 m/s. a) How much time does it take for the airplane to speed up to the take-off speed? b) How long does the runway need to be in order for the airplane to reach this speed? 26. You throw a golf ball off of the top of a building that is 14 m above the ground. The ball is initially thrown 12 m/s horizontally. a) How long does it take for the ball to hit the ground? b) How far away from the base of the building does the ball hit the ground? 3.
