January 26th & 27th, 2016 : Speed Machines worksheet

Remember to use the equation and equation triangle on your pink Motion Unit Outline!

Remember that there are 60 minutes in one hour and 60 seconds in one minute. Follow the set-up from #1 b. to convert hours or minutes to seconds for each problem. Below are hints to the answers to make sure you're in the ballpark of the right answer.

1. c. v>60 m/s

2. b. v>100 m/s

3. b. v<350 m/s

4. c. v~70 m/s

5. b. t<3000 s

6. a. d>7,000,000 m

b. d>10,000,000 m

c. d=<18,000,000 m

7. d<5,000,000 m

3. This is referring to an earlier problem. Be sure that your drawing is showing a change in velocity over time.

4. The equation is the same as your acceleration equation, just solved for final velocity. Use that with the time to solve for the final velocity since the initial velocity is 0 m/s. The last second is solved below (you don't have to show GUESS on your homework):

Be sure to add the values to the picture!

For part d you are solving for the distance using the new equation. The last second is solved below (you don't have to show GUESS on your homework):

1. The hawk starts off (initial velocity vi) at 4 m/s and accelerates to 9 m/s (final velocity vF) in 0.5 seconds (t). Write down those three values as your Givens, you're looking for the acceleration (Unknown). (10 m/s^2)

2. Anytime you read "stopped" or "at rest" the velocity is zero (0 m/s). In this case the initial velocity is zero. You are also given the final velocity and the time. The only thing missing is the acceleration. (<3 m/s^2)

3. This time you are given the acceleration, the initial velocity (10 m/s) and the time. The only thing you don't know is the final velocity. Multiply the acceleration by the time and you will have the change in velocity (~19). Remember that the change in velocity is [vf-vi] so if you add 10 m/s (vi) you'll have the final velocity. (<30 m/s)

4. This is similar to #2. (<0.5 m/s^2)

5. The bat starts off at 0.6 m/s (initial velocity) then speeds up and you don't know what the final velocity is. This is similar to #3. (<3 m/s)

6. This is similar to #2 and #4. (35 m/s^2)

7. If a driver comes to a stop their final velocity is 0 m/s. The initial velocity was 11 m/s and you know it took them 3.1 s to stop. You're solving for the acceleration (just like in #2, 4 and 6) but this time the acceleration should be negative. (>3 m/s^2)
