Data and Calculations Use the values calculated to create both position time and velocity time graphs for each type of motion. You
should create two graphs for each data set, one position - time graph and one velocity - time graph.
We will use the end of every 3rd interval out of 6 space intervals (3 spaces at 1/60 s per space to measure to
lab) as the midpoint and will be used as the times when we plot the data on the velocity - time graph.
Analysis Part
Part A Questions: Constant Velocity
1.
Determine the average speed of the cart using the total distance and total time measured.
2. Determine the average speed of the cart by choosing two points on your position - time graph, and
determining the slope of the line of best fit.
3. Describe how you can tell if an object is moving at constant velocity, just by looking analyzing the e
motion

if you already have the answer to (a), then just work out how many periods there are in 1 minute, and that's the answer to (c).

what is the instantaneous acceleration of

the particle at point b?

0 meters/second?

10 meters/second?

12 meters/second?

velocity imetersisecond

15 meters/second?

time (seconds)

answer: 0 meters/second^2

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
