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
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
Another method we first use the third equat...
