Answer:
option A is the correct answer for your question
Explanation:
pls makes me brainliest and follow
Given :
To Find :
Solution :
From the Free Diαgrαm :
Velocity in y - αxis is sαme
Therefore , Momentum in y - direction is conserved.
Chαnge in Momentum x - αxis
We know thαt,
Hence, the force αpplied by the wαll is 250√3N ( option A)
And we are done! :D
