Question

pls respond as soon as possible​

Answer 1

Answer:

for acceleration on car a

slope of line AB is (30/2)=15

as slope of vt graph gives acceleration

acceleration in first two hours=slope of line AB=15km/hr²

similarly

in b

acceleration=slope of line BC =0

2

area under vt graph gives total distance travelled

so,

in 'a' total distance travelled=area of ΔABC

in b total distance travelled=area of trapezoid ABCD
