A) \[5\,m\,{{\sec }^{-1}}\]
B) \[10\,m\,{{\sec }^{-1}}\]
C) \[20\,m\,{{\sec }^{-1}}\]
D) \[50\,m\,{{\sec }^{-1}}\]
Correct Answer: C
Solution :
Acceleration \[=\frac{\text{Force}}{\text{Mass}}=\frac{50\ N}{10\ kg}=5\ m/{{s}^{2}}\] From \[v=u+at=0+5\times 4=20\ m/s\]You need to login to perform this action.
