Dois blocos a e b de massas m e m, respectivamente, estão apoiados numa superfície horizontal perfeitamente lisa. uma força horizontal constante de intensidade f é aplicada ao bloco a.
a) aplique a cada um dos blocos a segunda lei de newton, também chamada de princípio fundamental da dinâmica (pfd) e obtenha duas equações escalares, relacionando as intensidades da aceleração.

b) calcule a intensidade da aceleração a e a intensidade da força f que um bloco exerce sobre o outro, considerando
f=12 n, m= 1,0kg e m=2,0kg

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98

t= half of the arc subtended by t.

r= half of the arc subtended by r.  

t+r= half of the arc subtended by t + half of the arc subtended by r= half of 360=180
