As decreases by half and increases to 4 times, the overall effect is that is doubled.
Hence, if we approximate the change in gravitational potential energy as the boy jumps to be , his maximum height is halved.
Kinetic energy increases and gravitational potential energy increases
Kinetic energy increases and gravitational potential energy decreases
Kinetic energy decreases and gravitational potential energy increases
Kinetic energy decreases and gravitational potential energy decreases
