For the velocity-time graph shown, what will be its velocity at t = 6s
Options
A
4 m/s
B
6 m/s
C
10 m/s
D
12 m/s
Answer & Analysis
Answer
D
Analysis
Calculate the acceleration a from the first
part of the graph (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
