Chap 2 and 3 Sample Problems A) Set up listing all knowns with a picture for questions 1-6. 1 ) A runner accelerates to a velocity of 5.36 m/s due west in 3.00 s. His constant acceleration is 0.640 m/s2 , also directed due west. What was his velocity when he began accelerating? 2) A car starts from rest and accelerates at 1.25 m/s2 for 10.0 s. What is its final speed? 3) A car starts from rest and accelerates at 1.25 m/s2 for 10.0 s. How far did it travel? 4) A car travels at 35.2 m/s for 2.00 minutes. How far does it travel? 5) A car traveling at 35.2 m/s decelerates to a stop in 11.5 s. What is the acceleration? 6) A car traveling at 35.2 m/s decelerates to a stop in 11.5 s. How far did it travel? B Write down the appropriate kinematic equation for questions 1-6. C) Solve the questions 1-6. D) Break the initial velocity into horizontal and vertical components. 7) 12.25 m/s at 30 8) 21.05 m/s at 250 F Set up and solve questions 9. A ball is launched at 12.25 m/s at 35 above the horizontal from the ground. How high does it go into the air? When after the launch does it reach the highest point
