Question

The velocity-time graph of a car moving along a straight road is
shown in figure. The average velocity of the car in first 25 seconds is​

Answer 1

Answer:

14 m/s

Explanation:

The graph which should have been there is attached.

We know that for a given curve, the average can be found out by finding the area enclosed by the curve and dividing it by the interval on the x-axis.

Here, the area enclosed is a trapezium.

Area of Trapezium = (1/2) × sum of parallel sides × Height

Area enclosed by the velocity curve = (1/2) × (25+10) × 20

                                                            = 350 m/s × s

Average velocity over the time interval 25 sec = 350/25 m/s

                                                                              = 14 m/s
