object. This change could be an increase in speed, a decrease in speed, or a change in direction. So, if a car travels around a circular track at a constant speed (of say for purposes of being specific 30 mi/hr), the car is in fact accelerating because the car is constantly changing direction.

The trailer ball; Each component is rated for the amount of weight it can haul. The lowest rating of the three components determines the overall rating of your total hitch system. For example, if you have a 3,500 lb. hitch and ball mount with a 2,000 lb. trailer ball, your hitch system is limited to the 2,000 lb. trailer ball towing capacity.

Dec 21, 2020 · Let m 2 = 2 kg. Let u 1 = 6 m/s. Let u 2 = 3 m/s. m 1 u 1 + m 2 u 2 = m 1 v 1 + m 2 v 2. Since the bodies are combined after the collision, v1 = v2. Let's call this velocity v. So: m 1 u 1 + m 2 u 2 = m 1 v 1 + m 2 v 2 = m 1 v+ m 2 v = (m 1 + m 2)v. Substituting: (5)(6) + (2)(3) = (5 + 2)v. 30 + 6 = 7v. So v = 36/7. What is Work?
