A body moves at 5 m/s for 4 s. What is the area under its v-t plot, and what does it mean?
A1.25 m, the time taken
B9 m, the final speed
C20 m, the displacement
D20 m/s, the acceleration
Answer & Solution
Correct answer: C. 20 m, the displacement
The rectangle area is 5 x 4 = 20 m, which is the displacement.
