4.3 HP 2 blocks

What does c₁ represent?

• The force of m₁ on m₂

• A constant

• The acceleration of m₁

The force of m₁ on m₂ is equal to

• the force of m₂ on m₁

• the force F applied from the left

• The acceleration

There are 2 forces called c₂ because

• of Newton's 3rd law

• there are 3 blocks

• of the force of gravity

In both problems, the normal force is

• equal to c₁

• equal to the weight

• equal to c₂

Why is Fnet = ma written as c₂ = m₁a?

• The net force is gravity

• The net force is the sum of the forces

• The net force is c₂

This is what we did in class, the force applied on the left F = (m₁ + m₂) a

If F = 12 N, m₁ = 1 kg and m₂ = 5 kg, what is a? ____ m/s²

• 1

• 2

• 3

• 6

c₁ = m₂ a and c₂ = m₁ a

mass 1 is smaller than mass 2 so
c₁​ (a)   c₂

• >
• <
• =
