Question

find the area of the shaded region in the graph (Fig 5) co 50 30 10 2017 5 30 5 velocity-time graph for a car moving with uniform acceleration​

Answer 1

Explanation:

Answer:Graph of the table : Draw X - axis and Y - axis on the graph with appropriate scale.

Let 1 cm = 10 s on X-axis.

Let 1 cm = 5 m on Y-axis.



(i) Acceleration means slope of graph AB

BC / AC = 30 - 5 / 50 - 0 = 25 / 30 = 0.5 m / s2

(ii) Distance travelled by car = Area of trapezium OABD

= 1 /2 (AO + BD) × OD

= 1 / 2 (5 + 30) × 50 = 875 m
