coef of friction = 9.60 ? That is very unusual.
Is a slap a slab ?
Is a flow something a floor?
There are two conditions here.
The first is before the block starts to slip on the slap and the static friction rules
In that case
F = 100 N
m = 40 + 10 = 50 kg
a = 100/50 = 2 m/s^2
Now will the block ever slip on the slab with a coef of 9.60?
F = 100 N
normal force = 9.81*10 = 98.1
maximum friction force = 98.1*9.60
so the block will never slip on the slab
HOWEVER I do not believe your 9.60
for reasonable friction if slipping:
F on block = 100 - mu*98.1
a block = (100 -mu*98.1)/10
a slab = mu*98.1 / 40
10kg block rest on top of a 40kg slap which rest on a frictionless flow. the coefficient of static and friction between the block and the slap are 9.60 and 0.40 respectively. the block is pulled with a force of 100 Newton. what are the acceleration of (a) the block (b) the slap
