What is the acceleration between two points on a velocity time graph which has coordinates
(10s, 15 ms-1)
and (20 s, 35 ms-1)?
A
1.7 ms-2
B
3.50 ms-2
C
1.00 ms-2
D
2.00 ms-2
Verified Correct Answer: D.
Physical Principles & Numerical Solution
Acceleration = \(\frac{\DeltaV}{\Deltat}\)
= \(\frac{V - U}{t_2 - t_1}\)
= \(\frac{35 - 15}{20 - 10}\)
= \(\frac{20}{10}\)
= 2ms\(^-2\)
