# A Nice Blend of Newton's laws and kinematics

**Classical Mechanics**Level 3

A block of **5 kgs** is kept rest on ground (of course of earth). Then a force of **100 Newtons** is applied vertically from downward on it , so that the block starts moving upwards. If the force is applied for **10 seconds** , and then withdrawn , find the maximum height (of course from ground) that the block reaches.Give your answer in meters.

Assume gravitational acceleration \(= 10 \left(\dfrac{m}{s^2}\right)\).
