A 1 kg mass on a rough horizontal surface is joined to a 2kg mass by a light, inextensible string over a frictionless pulley. Will the 1 kg mass move at a lower, higher or zero acceleration? Explain, based on Newton's laws of motion, and state the law. Answer this and I will mark it as brainliest.

Answer:
m
1
= 5 Kg and m
2
=10 kg
As the system is at rest, T= 50N
T−0.15(m+10)g=(10+m)a
a=0, for rest
50=0.15(m+10)×10
5=
20

(m+10)
3
100
=m+10
m=23.3 kg
