Question
lance traveled with known initial speed and acceteration (5 points) and immediately 14.0s. The train passes a station in London traveling with a constant speed of 3.0 m/s y accelerates without stoping from the station at a rate of 1.60 ms To distance it has traveled from the station in 14 s is: A. 42 m B. 157 a C. 199 m D. 53.2 m E. depends on train's weight and engine Linear vertical motion of a ball in free fall a ball vertically upward from the top of the North Classroom building with an of +16.0 m/s. Choose the y-axis positive upwards. Answer questions 8 and 9, showing governing equations and all work leading to correct answers (5 points) 8. What is the position of your thrown ball 2.00 s after you threw it (relative to where y threw it) ou A. y=12.4 m B. y=32.0m C. y-51.6m D. y=19.6 m E. none of the above oints) hat is the velocity of the ball 2.00 s after you threw it? =9.80 m/sExplanation / Answer
7] Use S = ut + (1/2)at2
=> S = 3(14) + (1/2)(1.6)(14)2 = 198.8 meters. [option C].
8] S = ut - (1/2)gt2
=> S = 16(2) - (1/2)(9.8)(2)2 = 12.4 m [option A].
