ID: C Problems (4 pts/ each) In the space provided, identify all given variables, write the appropriate equation, substitute & solve. Use acceleration due to gravity (g) = 10.0 m/s2. Show all work and answer in correct units. 21. What is the average speed of a runner that runs 25 miles in 10. hours? Given Formula Substituted Answer with Formula & Solve d: 25 miles correct units. 25 t: 10. hours 2. 5 miles /hour 22. A car accelerated from rest to 0.030 km/s in 6.0 s. What was the car's acceleration? Given Formula Substituted Answer with Formula & Solve correct units. f = 0.03 km/s t = 6.0 s a = Vf - V. 0-03- 0 0.005 Kim/$ lisz V1 = O 23. In 1947 Charles Yeager accelerated 8.00 m/s2 in 30.0 s to reach a final speed of 240 m/s. What was his initial speed? Given Formula Substituted Answer with Formula & Solve correct units. a = 8.00 m / 52 Vf = attvi / 240= 8(30)+vi om/ s t = 30s 240 = 240+Vi WE = 240m/s vi zo at rest 24, A penny is dropped from the top of the Empire State Building. Neglecting air resistance, what is its velocity after falling for 7.0 s? Given Formula Substituted Answer with Formula & Solve correct units. t = 7.09 a= vf- Vi 10 = Vf- 0 a = lom / sz 710 m/s Vi= o Vf = 706 sketch 25. How long did it take for a dropped penny to fall 135 m? at rest Answer with Given Formula Substituted correct units. Formula & Solve d= 135m d=zat tuit 135 = 2 (10)2 t a = com/s 135 = 3 (100 )+ 2.75/ VIZO 135 = 50+ 26. What is a dropped penny's velocity after falling 135 m? Given Formula Substituted Answer with Formula & Solve correct units. 1= 135m dzzatquit 135= 3(0) 2t Vi = O a= com/s t = 4F - vi 135=:50 + 27m/s * = 2. 27 . You throw a ball straight up at 35 m/s. The ball goes up and eventually stops. How far did the ball travel? Given Formula Substituted Answer with Formula & Solve vi = 35m/s correct units. t = VE- Vi t= 0- 35 a = com/s a -=- 3.5s 85m VE = 0 d = zat z + vit d = 2 ( 10 ) 2 + + 35 Equations: d = 150+35 Vavg= Ax Vavg= Vf+ Vi At 2 a = Vf - Vi t = Vf - Vi Vf = at + Vi t a = 1/2at 2 +vit - op v+2 = vi2 + 2a Dy
