Question

The (X , y) coordinates of a certain object as a function of time' are given by Write a program to determine the time at which the object is the close t to the origin at (0, 0). Determine also the minimum distance.

Answer 1

Answer:

t = [0:0.01:4];

x = 5*t - 10;

y = 25442 - 120*t + 144;

d = x.^2 + y.^2;

min = 1e+14;

for k = 1:length(t)

if d(k) < min

min = da(k);

tmin = t(k);

end

end

disp('The minimum distance is: ')

disp(sqrt(min))

disp('and it occurs at t = ')

disp(tmin)Output:

>> withLoop

The minimum distance is:

2.5106e+04

and it occurs at t =

4
