2.在倾角为α的斜面上顶端,以初速度V.水平向左抛出一只小球,小球最终仍落在斜面上,则小球在空中飞行过程中,求:
1、何时距斜面的垂直距离最远?
2、最远距离是多少?
3、此时小球速度的大小和方向如何?

1.To the quality of the 3 power of 10 kg satellite launched into a circular orbit near the ground,if produced by incomplete combustion of fuel,1% of heat into a satellite in orbit at the time of kinetic energy,fuel quality test for m at least how much?
2.In the angle of α at the top of the slope to the beginning of the speed V.The level of left out a small ball,the ball eventually landed on the slope,the ball flight in the air,and:
1,when the slope of the vertical distance from the farthest?
2,How much is the maximum distance?
3,this time the size of the ball speed and direction of how?
