Question

An object thrown vertically upward to the height of 20m comes to the hands of the thrower in 10seconds the displacement of the object is

Answer 1

ProvidEd that:

• Height = 20 metres
• Time taken = 10 seconds

To calculate:

• The displacement

Solution:

• The displacement = 0 m

Knowledge required: If the initial and final positions are same then the displacement became zero.

Explanation: As it's given that an object thrown vertically upward to the height and then comes to the hands of the thrower as here the initial position and the final position is same therefore, displacement becames 0 metre by itself!

→ Displacement = 0 m
