Object projected vertically upwardKinetic Energy problem.
Hi all,
An object is projected vertically upwards and reaches a maximum height of 250m. Calculate the kinetic energy and velocity when the object is 200m above ground while moving downwards.
To Calculate V:
Using V= √(2.g.s)
= √(2.(9.8).50)
= 31,305 m/s
But the book gives the answer as 10 m/s, how did they get this answer? What am I doing wrong?
