A 11000-kg truck moving east (E) at 9 m/s collides with a 3000-kg car moving in the opposite direction, west (W), at 45 m/s. If they stick together after the impact, how fast and, in what direction, will they be moving?

Please, show your work.

For general projectile motion, when the projectile is at the highest point of its trajectory, its acceleration is zero? a)the horizontal and vertical components of its velocity are zero. b) its velocity is perpendicular to the acceleration. c)the horizontal component of its velocity is zero. d)its velocity and acceleration are both zero.

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.
