SPHJU Worksheet Velocity-Time (v - t) graphs Name Date 1. The graph below shows the motion of an elevator in an elevator shaft over a 14.0 s time period. 3 Velocity, v (m/'s [Up]) 0 1p 14 Time, t (S) -1 -2 -3 a) How many times did the elevator stop? b) During the 14.0 s, how long was the elevator stopped? c) What was the elevator's displacement during the first two seconds? d) At what speeds can the elevator travel? ) What was the displacement during the last second? f) What was the displacement during the last two seconds? g) What was the displacement during the 14.0 s time period? h) What was the acceleration at t = 10.0 s? i) What was the acceleration at t = 12.0 s? j) When was the elevator going up and accelerating down? k) When is the elevator's speed at its fastest upwards? 1) What was the average velocity during the first two seconds? m) What was the average velocity from t = 4.0 s to t = 5.0 s? n) What was the average velocity from t = 11.0 s to t = 13.0 s? o) At what time is the elevator back at its starting position?SPH3U Worksheet Velocity-Time (v - t ) graphs 2. The graph below shows the velocity of a house fly in an air duct. 6 0 Velocity, v (m/s [E]) SG 10 Tine, t (s) 12 -2 -4 -6 a) What was the displacement of the fly during the first second? b) What was the instantaneous velocity of the fly at t = 3.0 s? c) What was the displacement from t = 10 s to t = 12 s? d) What was the acceleration of the fly at t = 9.0 s? e) During what time interval(s) was the velocity east, and the acceleration east? f) Att = 10.5 s, was the fly east or west of its starting point? g) During what time interval was the acceleration east and constant (uniform)? h) What was the acceleration of the fly at t = 7.5 s?SPHJU Worksheet Determining velocity Name from position-time (d - t ) graphs Date Velocity is given by the slope of a d-t graph: 40 30 Position, d (m) 20 10 2 4 B 10 12 14 Time, t (3) 10 O Velocity, v (m/'s) - PH 10 r- -PH -5 Time, t (8) : -10
