For the velocity-time graph shown, what will be its velocity at t = 6s
Options
A
6 m/s
B
20 m/s
C
12 m/s
D
15 m/s
Answer & Analysis
Answer
D
Analysis
Calculate the acceleration a from to ). Using the formula ,
with and , we get .
Since the graph is a straight - line, the acceleration is constant throughout.
Then, use the kinematic equation :
We want to find the velocity at
