can you please help me with this assignment, please show all the work.

This is Physics 20 (grade 11): Lesson 3 - Graphical Analysis of Uniform Motion

Question 16 An elevator moves up and down between floors in a building. The following graph shows the velocity of an Not yet elevator that was moving over a 15.0 s time interval. answered Marked out of 4.00 Flag 5.0 question Velocity (m/s) 0.0 -5.0 + 0.0 5.0 10.0 15.0 Time (s) a) What was the elevator's fastest speed? m/s. This occurs in the time interval between and seconds. b) What was the elevator's slowest speed? m/s. This occurs in the time interval between and secondsQuestion 17 A car manufacturer is testing a new sportscar on a straight driving track. Not yet answered The engineers track the car's velocity over different time intervals: Marked M f 0 3.00 seconds driving at +15.0 m/s 5.00 , Fl 0 7.00 seconds driving at +20.0 mls guess)\" 0 6.00 seconds driving at -30.0 m/s 0 4.00 seconds driving at +3.50 m/s Create a velocity-time graph and then use it to answer the following questions: a) What was the car's total displacement? b) What was the car's displacement in the FIRST 10 seconds? c) What was the car's displacement in the LAST 10 seconds? 2 marks for the graph, 1 mark for each question. Please upload your graph and clearly show your work and reasoning for each of the answers. l ["11 1 u; Paragraph 7 l} 1".5 ' g : vii
