Question

The motion of a car is described by velocity time graph as shown below Find distance in 0-20s and 20s-50s​

Answer 1

Step-by-step explanation:

1. To find the distance, we need to find area, So
2. area of triangle: 1/2*OC*AC: 25

so distance covered (0-20s): 25

3.First area of rectangle ABCD: 20*5: 100

Secondly, area of triangle BDE: 1/2*DE*BD: 25

Now add 100and 25: 125m

So From 0- 20s, body covers 25m

From 20- 50s, body covers

125m

Hope it will help you

Answer 2

Answer:

area of abdc= l*b= 20*5=100m                                 .........1

area of triangle bed= 1/2*b*h= 1/2*10*5= 25             ........2      

add 1 and 2

100+25

125m
