If an object of 0.550 kg is lifted from the floor to a height of 3.50m, how much work is done by the lifting force, what is the kinetic energy, and what is the velocity?

Isla’s change in velocity is 30 m/s, and hazel has the same change in velocity. which best explains why they would have different accelerations? isla had negative acceleration, and hazel had positive. isla had a different time than hazel. isla had positive acceleration, and hazel had negative. isla went a farther distance than hazel.
