Question

what is the solution ​

Answer 1

Answer:

A solution is a special type of homogeneous mixture composed of two or more substances know as solution

Answer 2

Answer:

option(b)  mV

Explanation:

Initial momentum of the ball perpendicular to the wall $p_{i}$  = m(−Vcos60° )

=  -mv/2

Final momentum of the ball perpendicular to the wall $p_{f}$ = m(Vcos60°)  

= mv/2

Thus impulse imparted to the wall I = $p_{f} - p_{i}$ = mV/2 - (-mV/2)

= mV
