Asked Jan 25, 2019

A body has a mass of 18 kg falls freely from rest. After falling 235 m, what will its velocity be just before impact. Neglect air friction

Step 1

Given information:

mass of the body=18kg

After falling height =235m

Then find the velocity before impact?

Step 2

The acceleration of the freely falling body=

Step 3

Here the body is freely falling from rest so U=0

Due to the conservation of energy law we consid...
