Question 13 (1 point) ✓ Saved (Theory problem) On its own, a tow-truck has a maximum acceleration of 5.20 m/s2. What would be the maximum acceleration (in m/s2) when this truck is towing & bus of twice its own mass? Round your answer to 2 decimal places.

Answer 1

$F_{max}=ma_{max}$ ----(1)

$F_{max}=(2m+m)a'_{max}$----(2)

Dividing (1) by (2),

amar 1 = 3dmax

$a'_{max}=\frac{a_{max}}{3}=\frac{5.2}{3}=1.73\ m/s^{2}$
