  1. Kinematics Quiz • A bicycle travels with a 4.5m/s velocity for 10 minutes. How far does it travel? • Rearrange the following equation d = ½ a t2 + vi t for initial velocity? • A train is accelerating at a rate of 2 km/hr2. If its initial velocity is 20km/hr what is its velocity after 30 second? • 4. An airplane traveling at 135m/s accelerates to 165 m/s during a 45 second interval of time. How far does the plane travel during this time?

  2. A bicycle travels with a 4.5m/s velocity for 10 minutes. How far does it travel? • Knowns • V = 4.5m/s • T = 10 minutes 10min x 60sec = 600sec • d = ? • V = d / t = d = v t 2700m d = 4.5m/s x 600sec = • Rearrange the following equation d = ½ a t2+ vi t for vifor initial velocity? d = ½ a t2+ vi t Step one: subtract ( ½ a t2 ) Step two: divide by t Vi = d - ½ a t2 / t

  3. A train is accelerating at a rate of 2 km/hr2. If its initial velocity is 20km/hr what is its velocity after 30 second? Kowns a = 2 km/hr2 V I = 20 km/hr t = 30 sec or .008 hr Vf = ? Vf = V I + a t Vf = 20k/hr + 2 km/hr2 .008hr= 20.016km/hr • 4. An airplane traveling at 135m/s accelerates to 165 m/s during a 45 second interval of time. How far does the plane travel during this time? Knows Vi = 135m/s Vf = 165m/s t = 45 sec d = ? d = (Vf + Vi) / 2 * t D = (165m/s + 135m/s)/ 2 * t = 6750m
