Asked Jan 25, 2019

A body has a mass of 11 kg falls freely from rest. After falling 553 m, what will its velocity be just before impact. Neglect air friction


Expert Answer

Step 1

There are two methods for calculating the velocity.

In first method by using the equation of motion we can calculate its velocity which is shown on the board

where v is the final velocity

u is the initial velocity

a is the acceleration due to gravity

s is the height 


Step 2

Another method we first use the third equat...
