Question

An overnight rainstorm has caused a major roadblock. Three massive rocks of mass ?1=528 kg, ?2=7.00×102 kg, and ?3=311 kg have blocked a busy road. The rocks are lined up from left to right in the order ?1, ?2, and ?3. The city calls a local contractor to use a bulldozer to clear the road. The bulldozer applies a constant force to ?1 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, ?A, must be applied to ?1 to slowly accelerate the group of rocks from the road at 0.100 m/s2?

?A=    N
 
Use the value for ?A to find the force, ?12, exerted by ?1 on ?2.
?12=     N
