t (s) | 0 | 1 | 2 | 3 |
x (m) | ?2 | 0 | 6 | 16 |
A) Uniform, accelerated
B) Uniform, decelerated
C) Non-uniform, accelerated
D) There is not enough data for generalization
Correct Answer: C
Solution :
Instantaneous velocity \[v=\frac{\Delta x}{\Delta t}\] By using the data from the table \[{{v}_{1}}=\frac{0-(-2)}{1}=2m/s.{{v}_{2}}=\frac{6-0}{1}=6\ m/s\] \[{{v}_{3}}=\frac{16-6}{1}=10\ m/s\] So, motion is non-uniform but accelerated.You need to login to perform this action.
