Question

4. Use the graph below to answer the following questions a) What is the displacement from time 0 to time 3 seconds? b) What is the average velocity from time O to time 3 seconds? c) What is the displacement from time O to time 6 seconds? d) What is the average velocity from time 0 to time 6 seconds? e) During which times is the object not moving? f During which times is the object moving with a negative velocity? g) During which times does the object accelerate in a positive direction? h) During which times does the object accelerate in a negative direction? -1 -- Time (seconds)

Explanation / Answer

4.

a)

d(0-3) = 3.0m

b)

vave(0-3) = d(0-3)/t(0-3) = 3.0m/3.0s = 1.0m/s

c)

d(0-6) = 1.0m

d)

vave(0-6) = d(0-6)/t(0-6) = 1.0m/3.0s = (1.0/6)m/s = 0.17 m/s

e)

During time t=2s to t=3s object is not moving

f)

During time t=5s to t=6s object is moving with negative velocity

g)

During time t=0s to t=2s and t=3s to t=5s object accelerate with positive direction

h)

During time t=5s to t=6s object accelerate with positive direction
