ANALYSIS II
Data Set 2. Imagine the following
experiment: A cart is initially at rest.
A force pulls the cart through a given distance and gives it an
amount of kinetic energy K. At the end of this distance, the
force goes to zero and the cart travels with a constant speed.
The resulting speed is measured. The data table on the next
page shows the measured kinetic energies and the measured
speeds.
K, Jv, m/s
0.50 0.48
1.50 0.76
3.00 1.10
4.50 1.30
6.00 1.55
7.50 1.70
1.
You wish to determine the relationship between kinetic
energy and speed. Speed is the independent variable and
kinetic energy is the dependent variable. Enter the data into a
graphing calculator or a data analysis program, plot the data
and examine the resulting graph.
Make a freehand sketch of the resulting graph. Include
axes labels (variable names and units) on your sketch. Does
the graph show a linear relationship?
2.
Consulting a physics text, you find the following formula
for kinetic energy, K = ½ mv² where K is…
I. A ball is dropped from 6.5 m above the ground. (Use g = 9.8
m/s^2 )
a) At what height is half of its energy kinetic and half
potential?
b) What is the velocity of the ball just as it hits the
ground?
A man drops a small ball from a very tall building. Assume that air resistance exerts a resisting force of 0.25v . mass = 0.1 kg
a) What is the speed of the ball after four seconds?
b) How far does the ball fall after four seconds?
