Explanation:
Definition formula for momentum: P = mv
So P(A) = 0.45 * 50 = 22.5 kgm/s
P(B) = 0.45 * 80 = 36 kgm/s
P(C) = 0.45 * 25 = 11.25 kgm/s
B has the greatest momentum
Answer:(a)360N,(b)171N,(c)2.702m
Explanation:
(a)Maximum Friction Force =
=360 N


(b)Moment about Ground Point




(c)

Here maximum friction force can be 360 N
Therefore 
Where x is the maximum distance moved by man along the ladder

740x=2000
x=2.702m
