$here \: is \: the \: answer \: of \: your \: question$

1. The answer of your your question is 50 m/s.

# Explanation :-

Accordingion we have given,

r = 500 m

μ = 0.5

g = 10

v = ?

So, the formula use here is,

v = √μrg

v = √ 0.5 x 500 x 10

v = √ 2500

v = 50 m/s

2. The answer is 2mnv

# Explanation :-

Now bullet hits the wall and also return with same speed v means,

mv - m(-v)

= mv + mv

= 2mv

Now, the rate of change of linear momentum for n number of bullet is,

= 2mv x n

= 2mnv
