A ball is thrown straight up with enough speed so that it is in the air for several seconds.
(a) What is the velocity of the ball when it reaches its highest point?
(b) What is its velocity 1 s before it reaches its highest point?
(c) What is the charge in its velocity, Δv, during this 1-s interval?
(d) What is its velocity 1 s after it reaches its highest point?
(e) What is the change in its velocity, Δv, during this 1-s interval?
(f) What is the change in its velocity, Δv, during the 2-s interval from 1 s before it reaches the highest point to 1 s after it reaches the highest point? (Caution: We are talking about velocity, not speed.)
(g) What is the acceleration of the ball during any of these time intervals and at the moment the ball has zero velocity?

- Three long, straight wires are mounted on the vertices of an equilateral triangle as shown in the figure. The wires carry currents of I₁ = 3.50 A, I2 = 5.50 A, and I3 = 8.50 A. Each side of the triangle has a length of 34.0 cm, and the point (A) is located half way between (11) and (12) along one of the sides. Find the magnitude of the magnetic field at point (A).

- Estimate the diameter of the Moon. During a total solar eclipse, the Moon passes in front of the Sun so that during “totality” their apparent sizes match and the Moon blocks light from the Sun shining on the Earth. a) What do you predict the size of the Moon would be if you were to use a pinhole in an aluminum holder, meter stick, and white paper screen to project light from the full Moon through a pinhole onto a screen that is one meter away from the pinhole? b) Describe in detail how you would use this apparatus and your knowledge of pinhole phenomena to estimate the diameter of the Moon. Assume that the distance between the Earth and the Moon is 250,000 miles.arrow_forwardThe following data was collected for a friction experiment in which an object was observed moving at constant speed over a surface.

Measurements and Linear Regression 1.1 Introduction The objective of this lab assignment is to represent measurement data in graphical form in order to illustrate experimental data and uncertainty visually. It is often convenient to represent experimental data graphically, not only for reporting results but also to compute or measure several physical parameters. For example, consider two physical quantities represented by x and y that are linearly related according to the algebraic relationship, y=mx+b, (1.1) where m is the slope of the line and b is the y-intercept. In order to assess the linearity between y and x, it is convenient to plot these quantities in a y versus x graph, as shown in Figure 1.1. Datapoints Line of regression Figure 1.1: Best fit line example. Once the data points are plotted, it is necessary to draw a "best fit line" or "regression line" that describes the data. A best fit line is a straight line that is the best approximation of the given set of data, and…arrow_forward
