A projectile of mass \( m \) is fired horizontally with an initial speed of \( v_0 \) from a height of \( h \) above a flat, desert surface. Neglecting air friction, at the instant before the projectile hits the ground, find the following in terms of \( m \), \( v_0 \), \( h \), and \( g \):(a) The work done by the force of gravity on the projectile. \[ W = \, \](b) The change in kinetic energy of the projectile since it was fired. \[ \Delta KE = \, \](c) The final kinetic energy of the projectile. \[ KE_f = \, \](d) Are any of the answers changed if the initial angle is changed? - [ ] Yes - [ ] No **Need Help?** [Read It]
