A truck on a flat road accelerates from rest at a constant rate
and covers a distance of 100 m in 6
s.
The mass of the truck is 900 kg.
What is the acceleration of the truck?
What is the net force on the truck?
The truck is now loaded with heavy equipment and has a NEW total
mass of 1300 kg.
If the same net force is applied to the car as calculated above,
then what would be the new acceleration of the
truck?
With this new acceleration, how much time would it take the (heavier) truck to travel 100 m starting from rest?
What would be the speed of the (heavier) truck when it reaches this point?

A car, starting from rest, accelerates in the +x direction as in the figure. It has a mass of 1.10 × 103 kg and maintains an acceleration of +4.30 m/s2 for 4.10 s. Assume that a single horizontal force (not shown) accelerates the vehicle. Determine the average power generated by this force.

A box rests on top of a flat bed truck. The box has a mass of m = 20 kg. The coefficient of static friction between the box and truck is mu_s = 0.86 and the coefficient of kinetic friction between the box and truck mu_s = 0.67. The truck accelerates from rest to v_f = 19 m/s in t = 12 s (which is slow enough that the box will not slide). What is the acceleration of the box?...
