Question

A body of mass 5kg is thrown up vertically with kinetic energy of 1000J.If acceleration due to gravity is 10ms-1, find the height at which the kinetic energy becomes half of the original value a) 10m b) 20m c) 50m d) 100m

plz ans fastly...​

Answer 1

Answer:

20g of mass is body transformation

Answer 2

Answer:

20m

Explanation:

as we know

K.E=P.E=mgh

m=5kg

K.E=P.E=1000j

g=10ms-1

By putting values

1000=5×10×h

1000=50×h

h=1000/50

h=20m
