Two bowling balls are rolling towards each other. The first has a mass of 5 kg and is rolling with a speed of 4 m/s to the right. The seconds has a mass of 6 kg and is rolling with a speed of 7 m/s to the left. After the collision, the first bowling ball rolls away with a speed of 5 m/s to the left. How fast is the second ball rolling after the collision? * a) 0.5 m/s
b) 7.5 m/s
c) 6.2 m/s
d) 0.9 m/s

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

the speed of the cart after 3 seconds of low fan speed is ⇒ 54.0 cm/s.

the speed of the cart after 5 seconds of medium fan speed is ⇒ 120.0 cm/s.

the speed of the cart after 2 seconds of high fan speed is ⇒ 64.0 cm/s. 

just did the lab.
