An overnight rainstorm has caused a major roadblock. three massive rocks of mass m1=584 kg, m2=838 kg, and m3=322 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, , must be applied to m1 to slowly accelerate the group of rocks from the road at 0.250 m/s2?

Force must be applied to m₁ to move the group of rocks from the road at 0.250 m/s² = 436 N

Explanation:

Total force required = Mass x Acceleration,

F = ma

Here we need to consider the system as combine, total mass need to be considered.

Total mass, a = m₁+m₂+m₃ = 584 + 838 + 322 = 1744 kg

We need to accelerate the group of rocks from the road at 0.250 m/s²

That is acceleration, a = 0.250 m/s²

Force required, F = ma = 1744 x 0.25 = 436 N

Force must be applied to m₁ to move the group of rocks from the road at 0.250 m/s² = 436 N

answer; i believe the correct answer is (40,000 j) good luck
