can you give me the code for these two questions?

Physics 1210 Homework 1 Written-out problems 1. X A truck traveling at 56 km/h (15.5 m/s) is 35 m from a wall when the driver hits the brakes. Four seconds later the car hits the wall. a) what was the truck's acceleration before impact? b) how fast was the truck traveling at impact? c) draw graphs of position versus time, velocity versus time, and acceleration versus time for the truck in Matlab and turn in your Matlab code. 1.Y Your reckless high school friend has a new sports car that can accelerate at a=3.2 m/s and wants to show off his wheels so he challenges you to a 14 mile race (402 m). You've only got a 1956 Ford truck that hardly accelerates at all (a=0), so you say it's only fair if he gives you a head start. You say that you can cross the start line at 20 m/s while he starts from rest at the start line. A) How much time passes before the car catches up with the truck? B) What what distance from the start line does the car catch up with the truck? C) What is the speed of his car when it catches up with the truck? D) Who reaches 4 mile first? E) Using the Matlab language, make a plot of the position of the car and the position of the truck versus time. Also make a plot of the velocity of the car and truck versus time. Turn in a copy of your matlab code with your graphs.
