Answer:

750 J

Explanation:

Using Conservation of Mechanical Energy

Let KInetic Energy at half way be x

So, Total Energy = K.E. at halfway + P.E. at halfway

1500=x+ 50×10×1.5 (Middle height = 3/2 =1.5)

x=1500-750

x=750 Joules

Kinetic Energy at middle point is 750 Joules

Answer:

after Half Fall, 1/2 of original PE is Now its KE

1/2 of 1.5 KJ = 1/2 m v ^2

so v^2 = 1500/ 50 = 30

v = Root 30 m per sec. at 1.5 meter during Fall.
