A 50 kg bobsled slides down an ice track starting (at zero initial speed) from the top of
a(n) 173 m high hill.
The acceleration of gravity is 9.8 m/s^2.
Neglect friction and air resistance and determine the bobsled’s speed at the bottom of
the hill.
Answer in units of m/s.

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
