LEARNING TARGET:

I will be able to solve intermediate momentum & impulse problems during today's class.

I will work on solving advanced momentum & impulse problems during today's class.

WORDS O' THE DAY:

• momentum (p=mv)
• impulse (∆p or F∆T

CALENDAR:

I'm thinking problems today and tomorrow, review on Wednesday and UNIT Test on Thursday (2/27/25)

FORMULAE OBJECTUS:

p=mv

J = F∆t = ∆p = p_f - p_i = m(v_f - v_i)

m_1iv_1i + m_2iv_2i = m_1fv_1f + m_2fv_2f

WORK O' THE DAY:

How can we quickly determine if a collision problem is inelastic?

Let us continue working on these beasties from the Physics Classroom:

Please go to the PhysicsClassroom Website and commence to work on just 1 of the first 9 problems to get back into the rhythm of things.

We'll spend time setting up the 'pencil' problem (#25). Let's see how far we can get before 9:15 and *then* review the answer.

We'll continue with these problems tomorrow:

Problem 15

Problem 18
