Question

2. (a) An object thrown vertically with a speed vo reaches a height h at time t, where: he vot tgt Write a MATLAB program with a user defined function that computes the time required to reach a specified height h, for a given value of vo. The function's input should be h, Vo, and g. Test your function for the case where h 100 m, Vo-50 m/s and g9,81 m/s2 by free hand. Write the MATLAB command how you will run/call the function with these given values. 110) logical (b) Write a flow chart and the script file using conditional statements with logical operator ifelse and if/elseif, to evaluate the following function, assuming that the scalar x has a value: te the following function, y = e-x+1 for x <-1 y = 2 sin(m) for-1 < 5 y 10(x-5)+ 1 for x 25 1101 Use your file to evaluate y for x =-5.x = 3 and x = 15 by hand

Answer 1

`Hey,

Note: Brother in case of any queries, just comment in box I would be very happy to assist all your queries

FUNCTION FILE

function t=fun(v0,h)
g=9.81;
    f=@(t) v0*t-0.5*g*t.^2-h;
    t=fzero(f,10);
end

Command needed to run

fun(50,100)

b)

clear all
clc
x=input('Enter x: ');
if(x<-1)
    y=exp(-x+1);
elseif(x<5)
    y=2*sin(pi*x);
else
    y=10*(x-5)+1;
end
fprintf('The value is %f\n',y);
