Question 103 of 183

As shown in the figure, a particle of mass $10kg$ is placed at a point $A.$ When the particle is slightly displaced to its right, it starts moving and reaches the point $B.$ The speed of the particle at $B$ is $xm{s}^{-1}$ . (Take $\left.g=10m{s}^{-2}\right)$ The value of $x$ to the nearest integer is

Show answer and solution

Answer: 10

Using work-energy theorem,

{W}_{g}=\Delta K.E.

(10)(g)(5)=\dfrac{1}{2}(10){v}^{2}-0

v=10m{s}^{-1}
