Question

A body thrown vertically upwards reaches a maximum height h . It then returns to ground. Calculate the distance travelled and the displacement?​

Answer 1

Explanation:

the length of the path covered is the distance..

and the shortest distance is the displacement.

e.g distance =2m

displacement=+1-1=0

Answer 2

Answer:

The elementary equations of ballistics neglect nearly every factor except for initial velocity and an assumed constant gravitational acceleration. Practical solutions of a ballistics problem often require considerations of air resistance, cross winds, target motion, varying acceleration due to gravity, and in such problems as launching a rocket from one point on the Earth to another, the rotation of the Earth. Detailed mathematical solutions of practical problems typically do not have closed-form solutions, and therefore require numerical methods to address.
