2. A cue stick strikes a stationary pool ball with a force of 50.0 N over a time of 0.0100 s. If the ball has a mass of 205 g, what velocity does it have just after impact?

9.98 kg of r-134a at 300 kpa fills a rigid container whose volume is 14 l. determine the temperature and total enthalpy in the container. the container is now heated until the pressure is 600 kpa. determine the temperature and total enthalpy when the heating is completed. use data from the steam tables.

Anika asks eva to roll a basketball and then a bowling ball to her. which requires more force to roll, and why?

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
