1. What is the smallest distance, in meters, needed for an airplane touching the runway with a velocity of 360 km/h and an acceleration of -10 m/s' to come to rest? v2 = d' + 2 at 2. A boy on a bicycle increases his velocity from 5 m/s to 20 m/s in 10 seconds. What is the acceleration of the bicycle? What distance was covered by the bicycle during the 10 seconds? 3. A car starts from rest and accelerates uniformly over a time of 5.21 seconds for a distance of 110 m. Determine the acceleration of the car. 4. An object with a mass of 59.50kg has a force of 90.50N applied to it What is the resulting acceleration of the object? 5. A softball has a mass of 1.5 kg and hits the catcher's glove with a force of 30 N? What is the acceleration of the softball? 6. A typical commercial jet airliner needs to reach a speed of 90 m/'s before it can take off. (A knot is a nautical mile per hour and is very nearly equal to half a meter per second) If such a plane spends 30 s on the runway estimate... a its acceleration. b. the minimum runway length 7. Cars cruise down an expressway at 25 m/s. Engineers are designing an off-ramp in an interchange with a deceleration of -2.0 m/s2 that lasts 3.0 s. What velocity will cars have at the end of the off-ramp? What minimum distance should the ramp have
