Question #58109

16 A 30,000-kg truck travelling at 10.0m/s collides with a 1700-kg car travelling at 25m/s in the opposite direction. If they stick together after the collision, how fast and in what direction will they be moving?

8.1 m/s in the direction of the truck's motion

12.3 m/s in the direction of the car's motion

24.2 m/s in the direction of the car's motion

17.6 m/s in the direction of the truck's motion

17 Sand drops at the rate of 2000 kg/min. from the bottom of a hopper onto a belt conveyor moving horizontally at 250 m/min. Determine the force needed to drive the conveyor, neglecting friction.
