Answer:

d) 1.44m

Explanation:

According to Newton's second law:

$\sum F=m.a\\$

analyzing the horizontal components of the force:

$\sum F_x=mg*sin(\theta)-\µ*m.g*cos(\theta)\\\sum F_x=m*9.8*(sin(16^o)-0.420*cos(16^o))\\\sum F_x=-1.25m$

applying the second law

$-1.25m=m.a\\a=-1.25m/s^2$

given the acceleration we can calculate the distances traveled before stopping:

$(v_f)^2=(v_o)^2+2.a.\Delta x\\0=(1.90m/s)^2-2(1.25)*\Delta x\\\Delta x=1.44m$

viktelen [127]

1000 miles = 1610km = 1.61x10^6m
2 weeks = 14 days = 14x24x1440

V=d/t = 1.61x10^6/14x24x1440
= 3.33m/s
