Mass is 10kg, constant velocity 5m/s, Ek=125Joules and gravitational acceleration is 9.81m/s^2. Hence, how high this object can climb an inline?

Based on the type of kinetic energy one could be discussing and then measuring one of the accepted formulas for kinetic energy is Ek=1/2 mv2

Kinetic energy of a body is given by the formula:
Kinetic energy (J) = ½ × mass × velocity²
This formula for kinetic energy is as required for GCSE level [UK]
KE = ½mv²
(Mass and velocity in kg and m/s respectively).
E.g. A 36kg boy is running at 3 m/s. His KE is:
KE = ½mv²
KE = ½ × 36 × 3²
KE = 18 × 9
KE = 162 J
Again KE is energy, so must be in joules (J).
