mechanics- D-T V-T graphs

Question 1

average speed in V-T graph

Answer 1

average speed = total displacement/total time taken

Question 2

average velocity in V-T graph

Answer 2

average velocity=total displacement/total time taken

Question 3

how to find velocity in D-T graph

Answer 3

m(velocity)=change in displacement/time

Question 4

how to find acceleration in V-T graphs

Answer 4

acceleration= change in velocity/change in time
