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