Question

problrma la fizica!!Urgent Am desenat deja toate fortele!!Dar nu pot rezolva!Va implor

Answer 1

Se da:
T=2,45N
m1=0,5kg
μ=0,1
a)m2=?kg
b)F=?kg

Rezolvare:
a)Pe corpul 2:

Ffr2=T

Ffr=μ×N2

N2=G2
N2=m2×g

Ffr=μ×m2×g

μ×m2×g=T
m2=T/(μ×g)

b)Pe corpul 1:
F=Ffr1+T

Ffr1=μ×N1

N1=G1
N1=m1×g

Ffr=μ×m1×g

F=μ×m1×g+T

Calcule:
a)m2=2,45/(0,1×10)=2,45kg
b)F=0,1×0,5×10+2,45=2,95N
