Explanation:
(i)the initial speed of the car is 10km/h.
(ii)the maximum speed attained by the car is 35km/h.
(III)BD represents zero acceleration.
(iv)CD represents varing acceleration.
(v) distance travelled is given by the area is enclosed within the curve,so
- distance travelled=Area of trapezium + area of rectangle
- the distance travelled ,
- =1/2(8+5)(25)+8(10)=242.5km
- I know this question that's why I done but didn't mention the graph
