Presentation transcript:

 Every variable in a kinematic equation (except for time) is considered a vector.  Vector drawing practice: › While playing golf, you notice that the fairway doglegs to the right up ahead. If you’ve traveled 100 m so far, and it’s an additional 75 m to the right before you reach the green, what is the magnitude of the resultant displacement and the direction (angle) of your golf ball once you’ve reached the green?

 To get to the football field from where you’ve parked your car, you must travel 28 o north of east for 0.48 km. Find the northward and eastward components of your trek.

 (a) is the rate at which velocity changes.  The equation to find acceleration is: a = (v f – v i ) t  Also shown as v f = v i + at  This is the only kinematic without displacement.

 Displacement can be in either the x or y direction.  The kinematic for displacement is: d = v i t + ½at 2  To solve this equation for time, you must use the quadratic equation, so don’t use this equation to solve for time.

 This kinematic does not have a clever name, but it is the only kinematic you can use if time is not given.  The equation is: v f 2 = v i 2 + 2a d  Most common mistake: Take the square root to find either velocity!

 The best 0-60 mph time listed for a mini cooper S is 6.9 seconds, whereas Mrs. Kittell’s MT mini cooper made 0-60 in 8.7 seconds. Hint: convert 60 mph to m/s first! › What were the mini cooper’s acceleration? › What is the difference in their acceleration? › (Is this worth the $4,000 price difference? )

 After the mini cooper hits 60 mph, it slows down at a rate of -2.2 m/s 2 for 30 seconds. How far has the mini cooper traveled?

 An individual in a truck decides to race a mini cooper. That individual floors it from a stop light and accelerates at a rate of 4.8 m/s 2 over a distance of 100 m. What was his final velocity?

 The individual in the truck is speeding along at 31 m/s when he spots a deer 70 m in front of him in the road. It takes him 0.8 seconds to react, then he slams on his brakes and decelerates at a rate of 8.3 m/s 2 in an attempt to avoid the deer. Does he hit the deer? › Prove your answer by finding his stopping distance.

 During a 100 m dash, the runners start off the blocks at the same time and the fastest accelerates at a rate of 1.6 m/s 2. How long does it take him and with what velocity does he reach at the finish line?
