Document Summary
The motion of the projectile is described by the kinematic equations. Separating the x and the y components we get: Along x: vx = constant, so vxf = vxi (uniform motion). The motion along x and y are independent, only time t links the two motions. Now repeat (a) of previous problem for a rabbit jumping from a height 0. 3 m above ground. Think: two identical balls roll off a tabletop. Just before rolling off the first ball is rolling at 0. 50 m/s and the second is rolling at 1. 5 m/s. Which ball hits the ground first: both land at the same time, the ball with initial speed of 0. 5 m/s, the ball with initial speed of 1. 5 m/s. Think: i throw a ball up in the air while i"m walking at a constant velocity. Where will the ball end up when it comes back down: in front of me, back in my hand, behind me.
