A spacecraft orbiting a planet goes out-of-control and starts falling towards the planet. The spacecraft falls 1200 m in the first 10 seconds, after which the retro-rocket fires and the craft starts to accelerate upwards at 0.5 g (1 g = 9.81 m/s 2 ) I also have to use the 4 kinematics equations.

Describe the path of a ray that approaches a mirror parallel to the principal axis.

Velocity is a description of both speed and direction, therefore it - a vector - a force arrow - the same as acceleration - a magnitude
