A car is driving on a highway at an initial speed of 20m\s. It holds this velocity for 5 seconds and then speeds up to 30 m\s over a time of 5 seconds.
a. what is the total distance the car has traveled in these 10 seconds.? (be very careful finding the area of the graph)
b.If the car continues speeding up at the same rate, how fast will it be going at the end of 20 seconds?
c. what is the acceleration of the car during the second 5 seconds?
Um i need a graph for each question (e.g. acceleration graph, velocity time graph, displacement time graph....etc. )
