A) \[1\,\,cm/se{{c}^{2}}\]
B) \[2\,\,cm/se{{c}^{2}}\]
C) \[3\,\,cm/se{{c}^{2}}\]
D) \[6\,cm/se{{c}^{2}}\]
Correct Answer: D
Solution :
Maximum acceleration means maximum change in velocity in minimum time interval. In time interval \[t = 30\, to t = 40 sec\] \[a=\frac{\Delta \nu }{\Delta t}=\frac{80-20}{40-30}=\frac{60}{10}\,\,=\,\,6\,cm/{{\sec }^{2}}\]
