5. Create the following a. Matrix prob5a: 0.1 0.2 0.3 0.4 0.5 0.6 0.7 1412 10 86 42 1 111 0 0 0 3 6 9 12 15 18 21 Matrixprob5b: a 3x4 matrix from the 1st, 2nd and 3rd rows, and the 1st through 4th columns of the matrix prob5a. Matrixprob5c: a 2x7 matrix from the 2nd and 4th rows, and all the columns of the matrix prob5a. b. c. Homework 2: Array Operations Designed to test skills with: element-wise operations, array transposition, vertical/horizontal array concatenation, and array arithmetic. ENGR 1221 Calculate the following in a script file. Terminate each line with a semicolon; use disp () answers to the command window to display final 1. The position as a function of time (x(t),y(t)) of a projectile fired with a speed of vo at an angle is given by: x(t) Vo cos(e)t ylt) Vosin()gt2 where g 9.81 m/s2 is the gravitational acceleration at the surface of the Earth. The distance from origin to the projectile at time t can be calculated by r(t) - x(t) y(t2. Set vo 100 m/s and 0- 79, then calculate x, y, and r for t-0, 2, 4.., 20 seconds, and store the results in row vectors. Use the variable names tl, x1, y1, and r
