A student wants to verify a claim that for a given change in momentum, the average applied force decreases as the time interval increases. The student plans to use a force sensor to produce graphs of force as a function of time for various trials of an experiment. Which of the following is the best method for the student to use to support the claim?
-
Drop an object onto the force sensor from the same height over multiple trials, varying the material on top of the sensor so the object is stopped over different time intervals.
A
-
Drop an object onto the force sensor from different heights over multiple trials so the object gains different amounts of speed during the drop.
B
-
Pull an object with the force sensor using the same force over different time intervals so the acceleration of the object is constant.
C
-
Pull an object with the force sensor using different applied forces over the same distance so the acceleration varies across trials.
D
-
Pull an object with the force sensor using different applied forces for the same time interval so the gains in speed vary. (E)
Homework Answers
A option is the best suited way to support the above said claim because in this , the change in momentum will be constant for every trial but the time of contact can be varied with changing material .

In order to estimate the average time spent on the computer terminals per student at a local university, data were collected from a sample of 81 business students over a one-week period. Assume the population standard deviation is 1.2 hours. If the sample mean is 9 hours, then the 95% confidence interval is approximately a. The 95% interval because it is a less accurate interval. The 95% interval because it is a less accurate interval. b. The 99% interval because...

Static Equilibrium Lab: Wheel and Axle
If you wanted to lift something heavy using this device, would
you have the heavy object connected to the larger disc and then
pull one the smaller disc, or vice-versa? Why? What would be the
effect of using this device on the speed that the object lifts?
That is, if you pulled your string at a speed of 10 cm/s, would the
object lift 10 cm/s, or would it lift faster or slower?

A physic student sets out to experiment on the effect of drag forces on a ball of mass m by giving the ball an initial velocity nu_0 upwards and then downwards as describe below. In both cases, the ball experiences a force of air resistance whose magnitude is given by F = -k nu Where k is a positive constant. The positive direction for all vector quantities is taken to be upwards. Express all algebraic answers in terms of m....
