Physics 10-5-21 More Angular Projectiles & the Monkey-Hunter Problem

PHYSICS – Great job today working through the monkey-hunter problem!

Do the problems make more sense now?Now go and tackle #36. Don’t give up on it. It’s tough, but you can do it!

If you need some inspiration – here are links to some Monkey-Hunter videos

Physics 10-4-21 Angular Projectile Problems

PHYSICS – Great work today for a Monday! I love the way you are thinking through the angular projectile homework problems. We looked at #35 – the kicked football, and #62 – the accelerating rocket. Also did a bit of a heads up on #59 – jumping on Earth and Mars.

UPDATE: For tomorrow, add this monkey/zookeeper problem below to the 2D Motion Worksheet:

A zookeeper finds an escaped monkey hanging from a light pole. Aiming her tranquilizer gun at the monkey, she kneels 10.0 m from the light pole, which is 5.00 m high. The tip of her gun is 1.00 m above the ground. At the same moment that the monkey drops a banana, the zookeeper shoots. If the dart travels at 50.0 m/s, will the dart hit the monkey, the banana, or neither one?

Physics 10-1-21 Angular Projectile Motion

PHYSICS – So we are finally putting it all together – angular projectile motion! Here’s the lesson – some homework discussion and then angular projectile motion.

The number one thing to remember – Never use the resultant velocity to do more than find the vertical and horizontal components! And vertical is vertical, horizontal is horizontal and don’t ever mix the two!

Spoiler alert: I couldn’t stand leaving the monkey-hunter problem hanging, so I went ahead and finished it for you.

Physics 9-30-21 Horizontal Projectile Motion

PHYSICS: Great job today – and applying stuff from the last chapter no less!

Just go slow and easy, talk yourself through what you are doing and ask if the formulas you are using are legit. You’ll master it in no time flat. Watch out for squirrels throwing nuts!

Physics 9-29-21 Relative Motion Revisited

PHYSICS – How’d you do with relative motion “revisited”? You know, you’ve done this already. The only new part is the motion of objects in the same direction and opposite directions, relative to each other. Don’t forget, you’ll use what you learned about vector addition to work those “boat goes across a river” and “plane experiences a head wind” types of problems. You’ve got this!

Physics 9-13-21 Free Fall HW Problems 2

PHYSICS: Here’s our look at the second set of free fall homework – #36 and #48, the students on a balcony and the second rocket problem. Below that is the help session from this morning – falling flower pots and the pelican.

Are you becoming more comfortable with working problems? When selecting formulas, it’s always a good idea to ask yourself “Why?”. Why can you use this formula? Why is it legit? Why is it the best one? Is there a better route to the solution? And then, continue to practice them over and over til it starts to become second nature!
