The diagram above illustrates the velocity-time graph of the motion of a body. Calculate the total distance covered by the body
Attached Figure / Diagram
A
50m
B
65m
C
175m
D
225m
E
300m
Verified Correct Answer: D.
Physical Principles & Numerical Solution
Distance of A = 1/2 x (10 + 20) x 5
= 1/2 x 30 x 5 = 75m. Distance of B = 20 x 5 = 100m
Distance of C = 1/2 x 5 x 20 = 50/225
∴ Total distance is 225m
