How much force crosses the contact?
A 12 N horizontal force pushes a 2 kg block against a 4 kg block on a smooth table.
Find the contact force on the 4 kg block.
Organize the givens & assumptions
- F = 12 N
- m₁ = 2 kg (left, directly pushed)
- m₂ = 4 kg (right)
Smooth horizontal table; rigid blocks remain in contact; applied force acts on the 2 kg block.
- A
- B
- C
- D
