Answer 1

Answer:

$\red{\bold{b)\:}}$The net $\green{\bold{displacement\:}}$by the ball is $\orange{\bold{zero.}}$

Explanation:

$\red{\bold{Distance\:⟹}}$ 50 + 50 = 100m

Distance is 100m because We know that ,

What is the Distance ?

⟹ Distance is defined as the actual path travelled by a body .

$\red{\bold{Displacement}}$ will be zero (0) because ball returns back to the same position .

$\green{\bold{Displacement}}$ is defined as the shortest distance between actual or final position .
