The distance traveled by a ball falling in the air is given by the equation Use MATLAB to calculate the position of the ball at time r-ss, if -10m, vo- 15 m/s, and a=-981m/sec 2 6. Suppose that x = 3 and y=4. Use MATLAB to evaluate the following expression: 7. What is the difference between an array, a matrix, and a vector? 8. Answer the following questions for the array shown here 1.1 3.2 3.4 0.6 0.6 1.1-0.6 3.1 1.3 0.65.5 0.0 a) What is the size of C? b) What is the value ofC (2.3) c) List the subscripts of all elements containing the value 0.6 9. Determine the size of the following arrays. Check your answers by entering the arrays into MATLAB and using the whos command or the Workspace Browser. Note that the later arrays may depend on the definitions of arrays defined earlier in this exercise a) u-[10 20*i 10+20], b) v-[-1; 20, 3: e) w [10-9,2-20:123] e) y (3,3)--7 D z-[zeros (4,1) ones (4,1) zeros (1.4)1
