Question

Fill out the table and do parts 2 and 3

Table 1.1: Behr free-fall pos/ time data. dot # 1 time (s) | position (cm) velocity (cm/s) 0 60 2/60 60 10.00 11.88 14.10 16.50 and 2, (14.10 - 10.00)em i02- -30(410)cm1/s#123cn/s and between dots 1 and 3. Place them in the table at the times they are the instantaneous velocity: for example. the time at which the average velocity between dots 0 and 2 is the instantaneous velocity is the time 60 note this is the time at whicı dot 1I was produced Similarly ias is the instantaneous velocity at t 2. Make a plot I vs. f using the data in Tah. Ll aud stinate the slope of the straight line describodl by the dnts 3. Calculate the percentage eino? betwecr you n slope and the awwpted val ue for the acceleratiow due to grawity osm

Answer 1

Since in free fall, distance covered by a body = displacement Therefore velocity = Change in displacement/Delta t V_O 2 = (11 .88 - 10 . 00) cm/(1/60 - 0) s { Because see the table } V_O 2 = 1 . 8 8 times 60) cm/s V_o 2 = 112 . 8 cm/s V_O 2 = (14.10- 10 .00)/(2/60 - 0) S = 123 cm/s V_o 3 = (16 . 50 - 10 . 00) cm/(3/60 - 0) V_o 3 = 6. 5 times 60 cm/s/3 V_o 3 = 130 cm/s \ r \ n \ stop tan theta = 123 - 112/(2/60 - 1/60)
