Answer:

velocity will be √10

Step-by-step explanation:

the potential energy at point A = mgh = m•g

and there is no kinetic energy as we know so the Total energy of system = E = m•g

Now at point B the potential energy is converted to kinetic energy

So, E = P.E + K.E

mgh + 0.5 mv^2 = g•m

solving this we get , v^2 = 10

so v=√10

Answer:

velocity will be zero

so,

potential energy + kinetic energy

mgh +0.5mv^2 = g. m.

v^2=10

v=10
