An object is kicked at 25.0 m/s [40.0°) on Groot's home planet. What is the range (x distance) of the object on level ground? (The acceleration due to gravity
on Groot's planet is 18.0 m/s

Determine the fraction of the magnitude of kinetic energy lost by a neutron (m1 = 1.01 u) when it collides head-on and elastically with a target particle at rest which is 21h (heavy hydrogen, m = 2.01 u).

(**i would really appreciate if this was answered soon** ) which pair of quantities includes one quantity that increases as the other decreases during simple harmonic motion?
