In summary, Quick Starter Questions are a series of short, simple questions designed to quickly engage students and activate their prior knowledge on a topic. They are different from other types of questions as they are specifically designed to be short and simple and are intended to be used at the beginning of a lesson or activity. These questions can benefit students by helping them activate their prior knowledge, make connections, and increase their motivation and interest in the lesson or activity. They can be used in any subject or grade level and to come up with effective questions, one should consider the learning objectives and the prior knowledge of the students and use a variety of question types.

1. A speed skater moving across frictionless ice at 8.20 hits a 4.60-m-wide patch of rough ice. She slows steadily, then continues on at 5.30 .
SLC: I am assuming that Vf = 5.3 m/s ; Vi = 8.2 m/s ; d = 4.60 m ; a =? ; t = ?.
Can you get me started with a correct forumula? I am fairly certain I can get the answer from there.

Thanks!

Vf^2 = Vi^2 + 2a(d)

d = Vi (t) + .5at^2

These are two of the general equations for kinematics.

Sure, the correct formula to use in this scenario would be the equation of motion: Vf^2 = Vi^2 + 2ad, where Vf is the final velocity, Vi is the initial velocity, a is the acceleration, and d is the distance traveled. From there, you can rearrange the equation to solve for either a or t, depending on which variable you are looking for. I hope this helps get you started!
