A) \[2m/{{s}^{2}}\]
B) \[4m/{{s}^{2}}\]
C) \[6m/{{s}^{2}}\]
D) \[8m/{{s}^{2}}\]
Correct Answer: B
Solution :
[d] If a is the acceleration of the cart, then \[ma\frac{h}{2}=mg\times r\] \[\Rightarrow a=\frac{2gr}{h}=\frac{2\times 10\times 2}{10}=4m/{{s}^{2}}\]You need to login to perform this action.
