In the Figure an Airport Luggage Carrying Train with a Tractor

Multiple Choice

In the figure an airport luggage carrying train with a tractor $T$ is pulling three luggage carts $M_{1}, M_{2}$ , and $M_{3}$ , with constant velocity of $4.5 \mathrm{~m} / \mathrm{s}$ . Unfortunately, the wheels on the carts have locked up and are sliding rather than rolling. If $T=300.0 \mathrm{~kg}, M_{1}=200.0 \mathrm{~kg}, M_{2}=100.0 \mathrm{~kg}$ , and $M_{3}=100.0 \mathrm{~kg}$ , and the coefficient of kinetic friction for each is 0.4000 , what is the force in the connection between the tractor $\mathrm{T}$ and cart $\mathrm{M}_{1}$ ? Use $\mathrm{g}=9.8 \mathrm{~m} / \mathrm{s}$ .

A) $1862 \mathrm{~N}$
B) $1568 \mathrm{~N}$
C) $2941 \mathrm{~N}$
D) $2744 \mathrm{~N}$
E) $2439 \mathrm{~N}$
