Two vehicles of mass M and 2M are moving in the same direction on a highway. Both drivers apply their brakes at the same time an

d both vehicles begin sliding. If the coefficient of kinetic friction μk is the same for both vehicles, how do their accelerations a1 and a2 compare?

Answer:

The mass is inversely proportional to the acceleration so the acceleration a1 is twice that acceleration a2

a_{1},a_{2}=\frac{a_{1}}{2}

Explanation:

The force of friction and the kinetic force make the law of mass in moving so

F=m*a

F=f_{m}+f_{k}

f_{k1}=u*m1*g

f_{k2}=u*2*m1*g

f_{m}=\frac{1}{2}*m1*v^2

The forces are the same however at the moment to determinate the acceleration

a_{1}=\frac{F}{m}

a_{1}=\frac{F}{2*m}

\frac{F}{m} are constant because they make the same motion however the difference of mass make the acceleration difference
