Friction :
a 5kg box on a horizontal table is pushed by a horizontal force of 35N as shown on the right . if the coefficient of friction is 0 .4 .
A- what is the frictional force
B - what is acceleration

Explanation:

a.

F=¶N

f=force

¶is the representation of co-efficient of friction.

¶=0.4

N represents mg which is mass*gravity

f=0.4*(5*9.8)

f=19.6N

b.

f=ma

where m=mass of the box

a=acceleration

f=force

a=f/m

a=19.6/5

=3.92m/s2
