Acannon on a railroad car is facing in a direction parallel to the tracks. it fires a 97.00 kg shell at a speed of 105 m/s (relative to the ground) at an angle of 60.0° above the horizontal. if the cannon plus car have a mass of 4.9 × 104 kg, what is the recoil speed of the car if it was at rest before the cannon was fired?

This is the substance(s) formed in a chemical reaction.

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].
