A) a uniform velocity
B) a uniform acceleration
C) increasing acceleration
D) decreasing acceleration
Correct Answer: B
Solution :
[b] Given, \[s=c{{t}^{2}}\], |
Here, c = constant of proportionality |
\[\therefore \operatorname{Acceleration},\ a=\frac{{{d}^{2}}s}{d{{t}^{2}}}=\frac{{{d}^{2}}}{d{{t}^{2}}}(c{{t}^{2}})\] |
=2c constant |
So, the object is moving with a uniform acceleration. |
