1 Overview Ballistics is the science of projectile motion and impact, phenomena well described by Newtonian mechanics. The number of applications of this type of analysis is staggering, ranging from such mundane issues as automobile accident simulations and optimal golfing to the critical studies of missile defense and space exploration. Somewhat less dramatically, in this project we will use Newtonian mechanics to describe the flight of a sponge dart, light enough so that air resistance will play a critical role. 2 Experimental Data The data for this project was collected by firing sponge darts from a toy gun ($3.99, WalMart). The table below shows a set of measurements for distance traveled (by the projectile) versus angle of inclination of the gun, taking angles of inclination 5, 10, 15, . 85 degrees. The darts were fired from a height of . 18 meters. Angle of 5 Inclination Distance 10 15 20 25 30 35 40 45 4.37 5.23 6.95 7.84 8.17 8.69 8.81 8.99 8.95 Traveled Angle of Inclination…

ANALYSIS I Data Set 1. Imagine that a cart is rolling smoothly along alevel track as shown in the diagram at the right. A motion detector, placed at the left end of the track, records the position of the moving cart at equal intervals of time. Assume that the forces of friction are very small and can be neglected in your data analysis. The motion data is shown below. t, s x, m 0.20 0.69 0.40 0.80 0.60 1.18 0.80 1.29 1.00 1.69 1.20 1.83 You wish to learn the relationship between position and time. Time t is the independent variable and position x is the dependent variable. Enter the data into a graphing calculator or a data analysis program, plot the data and examine the resulting graph. Often, it is best to plot data as points only and omit the connecting lines between points. Most plotting programs allow you to display plotted data either way. 1. 2. Make a freehand sketch of the resulting graph. Include axes labels (variable names and units) on your sketch. Does the graph show a…

Answer in 2 decimal places.  Dynamics of Rigid Bodies A particle moves that is defined by the parametric equations given below (where x and y are in meters, and t is in seconds). Compute the transvers component of the velocity (m/s) at t = 2 seconds. x = 3t2 - 1 ; y = t3 - 3t2 + t - 3

Part A Suppose the instructions for a scavenger hunt tell you to walk 6.2 km west, 7.3 km south, 9.6 km east, then 3.4 km north. How far will this scavenger hunt take you from the starting point? Express your answer with the appropriate units.   B. In what direction measured south from east will you end up from the starting point? Express your answer in degrees.

Task 3 As a part of your role in the motion and dynamics analysis department, you have been asked to design a mission consists of airplane and boat. The mission target is to deliver a package by the airplane that must be picked by the boat. You must provide two analysis steps to solve the problem: 50 m/s Package Figure.2: Package of emergency supplies Part 1 • The airplane traveling horizontally at 50 m/s • The airplane is 150 m above the sea 9. Write the displacement vector r* as a function of time and find by calculus the acceleration vector a". 10. Compare the acceleration vector you have got from Part.9 with the known projectile motion values. 11. What is your student ID?

A & b please

Dynamics of Rigid Bodies Cars A and B approached each other on a straight road from points 460 m apart. Car A has an initial speed of 70 kph and is decelerating at the rate of 0.40 m/s^2. Car B has an initial speed of 20 kph and is accelerating at the rate of 0.30 m/s^2. When will the cars meet and how far will each have traveled? Draw the figureproperly. No figure no point.

110 FORCES AND EQUATIONS OF MOTION However, the integral is simply the total mass of the sphere, and we find that for r > R, the force between m and the sphere is identical to the force between two particles m and M separated a distance r. Problems For problems marked *, refer to page 520 for a hint, clue, or answer. 3.1 Leaning pole with friction Two identical masses M are pivoted at each end of a massless pole of length L. The pole is held leaning against frictionless surfaces at angle 6, as shown, and then released. Find the initial acceleration of each mass. 3.2 Sliding blocks with friction* Mass MA = 4 kg rests on top of mass Mg = 5 kg that rests on a fric- tionless table. The coefficient of friction between the two blocks is 4 kg 5 kg such that the blocks just start to slip when the horizontal force F applied to the lower block is 27 N. Suppose that now a horizontal force is applied to the upper block. What is its maximum value for the blocks to slide without slipping relative to…

can you help with number 1?

Hello, I need help with part A and Part B and Part C I just don't understand the problem I was wondering if you help me with the problems and can you label which one is which. Thank you so so so much

Answer Requested The graph of a proportional relationship is a straight line that passes through the origin: y = Cx 4C- When we double x, y doubles as well. 2C- 2 Notice that when the x value increases by 1, the y value increases by C·1, and when the x value increases by 2, the y value increases by C. 2. 1 In the graph that you just drew, C = 1/2. Therefore, when the x value increases by 1, the y value increases by 1. How much does the y value increase when the x value is increased by 3? For the following parts, use the fact that when an object is moving at constant velocity, position s and time t are related by s = vt + so , where v is the speed of the object and so is the position at time zero in the chosen coordinate system.
