A descent vehicle landing on Mars has a vertical velocity toward the surface of Mars of 7.0 m/s.At the same time,it has a horizontal velocity of 2.5 m/s.
(a) At what speed does the vehicle move along its descent path?
(b) At what angle with the vertical is this path?
翻译:很多语法是错的,大概看下吧,应该是对的.
一个血统车登陆火星上有一垂直向火星表面7.0米/秒的速度.在同一时间,它有一个水平的速度为2.5米/秒.
(一)以什么速度的车辆沿着它的下降路径?
(b)于什么样的角度与垂直这条道路?
