Explanation:

The velocity-time graph of a body is given below. Find the average velocity from

to

Answer 2

Answer: AVERAGE VELOCITY=20m/s

Explanation: Average velocity=Total displacement/Time

The area enclosed by the velocity-time graph gives the displacement.

So,we have to find out the area of the triangle, rectangle, and trapezium.

Area of the triangle=1/2x20x20=200

Area of the rectangle=10x20=200

Area of the trapeziuum={(20+60)/2]x10=400

Therefore Total displacement=200+200+400=800m

Time taken=40-0=40s

Average velocity=800m/40s=20m/s
