The key objective of this video is to consider a problem to work out on velocities of object following an impact. First part of the video jumps straight to the brief on the given exemplary problem where it has said a b’ute is speeding down a highway & rear-ends a hatch-back. If the b’ute was travelling at 130 km/hr and the hatch-back at 90 km/hr just before the collision, calculate the velocities after impact. Given the coefficient of restitution is 0.5. Moving on, the video vividly explains the physical occurrence highlighting all the facts and figures in greater details.

Next, the video step by step shows how to find initial and final momentum and subsequently shows how to relate them to finally calculate the value of velocities after impacts using the given value of coefficient of restitution. Overall, the video illustrates a comprehensive workout on central impacts example understanding which is very essential for the study of engineering mechanics.

### Course Description

Mechanics, the study of forces and physical bodies, underpins a very large proportion of all forms of engineering. A thorough understanding of mechanics is essential to any successful engineer. This course helps develop an understanding of the nature of forces with consideration for how they may be simplified in an engineering context. The conditions of equilibrium are then used to solve a number of problems in 2D and 3D before moving on to a broad range of topics including centroids, distributed loads, friction and virtual work. The course will also provide an introduction to dynamics, with a particular focus on the effects that forces have upon motion.
