The objective of this video is to use rectilinear concepts overviewed in last video to solve exemplary problems. At first, the video presents a problem of a man dropping a ball off a cliff. The video asks to calculate how tall is the cliff if the ball is travelling 40 m/s just before it hits to the ground. Moving on, the video overviews the problem through a schematic drawing & subsequently shows the three formulas described in previous video. The video, then, explains how to choose the required formula wisely to solve the problem based on the data and information available.

Second part of the video presents another problem of rectilinear motions where it has asked to find how much time is required to reach a terminal velocity of 60.0 m/s when a skydiver jumps out of a plane. Moving on, the video briefly shows how to assess parameters values from the given data and successively determines the time required to reach the stated terminal velocity. Overall, the video is tried to give an overview on the use of formulas of rectilinear motion in solving different problems.

### 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.
