Using MATLAB:

The velocity, v, and the distance, d, as a function of time, of a car that accelerates from rest at constant acceleration, a, are given by

= a n d = 12

Determine v and d at every second for the first 10 seconds for a car with acceleration of = 15 ft/s2. Your output must have exactly the same format as the template table below. Note that dots have been added to the table below; you can count the dots to determine the exact spacings. Also note the units.

··········Time (s) ······· ···Distance (ft) ·········Velocity (mph) ··········x.x·················x.xxe+yy···············x.xxx

Expert Solution

MATLAB CODE

clear
clc;
a = 15; %ft/s2 (acceleration)
for i = 1:10
    t(i) = i; %time span
    d(i) = 12 + (1/2)*a*t(i)^2; % initial distane is 12 ft.
    v(i) = a*t(i)*(3600/5280); % 1 mile = 5280 ft and 1h =3600 sec
end
table = [t' d' v']

Ans

Time(s)	Distance(ft)	velocity (mph)
1.0000	19.5000	10.2273
2.0000	42.0000	20.4545
3.0000	79.5000	30.6818
4.0000	132.0000	40.9091
5.0000	199.5000	51.1364
6.0000	282.0000	61.3636
7.0000	379.5000	71.5909
8.0000	492.0000	81.8182
9.0000	619.5000	92.0455
10.0000	762.0000	102.2727

Write a MATLAB script or function that returns the required initial velocity of the ping pong ball required to launch it a specified distance. Use projectile motion equations. Keep in mind that the initial firing height will change depending on the proposed catapult design. Primary considerations in the catapult design are accuracy and repeatability as groups will be tasked with hitting the target (cup) repeatedly at distances ranging from 7 to 9 ft. (cup moved in 6 in. increments).

A particle moves along a line with velocity function ?(?) = ?^2 − ?, where v is measured in meters per second. a. Find distance traveled by the particle in time interval [0, 6] seconds. b. Find the net displacement. 8. Estimate the area from -1 to 9 under the graph of f(x) = 81 – x^2 using five approximating rectangles and midpoints as sample points.

For example, a definite integral of a velocity function gives the accumulated distance over the period. You should also be growing more comfortable with how the units work – for example, integrating meters per second with respect to seconds gives meters.Your job is to find an article that refers to a definite integral. It is possible that you will be able to find an explicit mention of a definite integral. Much more likely, though, the definite integral will be implied...
