Question
An overnight rainstorm has caused a major roadblock. Three massive rocks of mass m₁ = 514 kg, m₂ = 7.00 x 10² kg, and
m3 = 366 kg have blocked a busy road. The rocks are lined up from left to right in the order m₁, m2, and m3. The city calls a
local contractor to use a bulldozer to clear the road. The bulldozer applies a constant force to m₁ in order to slide the rocks off
the road.
Assuming the road is a flat, frictionless surface and the rocks
are all in contact, what force, FA, must be applied to m₁ to
slowly accelerate the group of rocks from the road at
0.400 m/s²?
Use the value for FA to find the force, F12, exerted by m₁ on
m₂.
FA =
F12 =
N
N
