Use the velocity equation ?- +0.81 to calculate the velocity, the position, and acceleration of the projectile at time t4s. When the program ran it must display the velocity v, position s, and acceleration a. Helper: Example 12.1 page 10: clear all 602 Data syms t T0-0 1-3: S0-0: % Position s-int (, TO,T1) % Acceleration andiff (v,t) a=eval(a) ; Display results End :50 PM 9/2018

Explanation / Answer

MATLAB SCRIPT

clc
clear all
syms t
v=(1/60^2+0.8*t)^(-1/2);

p=int(v,t); %Integration for position
Position=double(subs(p,t,4))
Velocity = double(subs(v,t,4))
a=diff(v,t,1); %diffrentiation for acceleration
Accleration= double(subs(a,t,4))

RESULTS

Position =

4.4723

Velocity =

0.5590

Accleration =

-0.0699
