Question

find distance travelled from t=0 to t=10​

Answer 1

Answer:

200 m is the distance travelled

Explanation:

Distance travelled is the area of the graph.

The area of the triangle is the distance. The distance can never be negative and hence, no negative value will come.

the base of the triangle = the time travelled which is 10

the perpendicular of the triangle is 20+|-20| = 40. Since distance has no negative, we add the modulus of the negative

The area of the triangle enclosed by velocity - time graph gives distance,

The area is = 0.5X 40 X 10 = 200m

The distance travelled is 200 m

Answer 2

Answer:

distance = 200m

Explanation:

To find : distance

distance = speed × time

=> distance = area under velocity-time graph

area = area of triangle (1) + area of trapezium (2)

=> area = (1/2)(20)(5) + (1/2)(5+10)(20

distance & area are scalar so cannot be negative

=> area = 50 + (10)(15) = 50 + 150

=> area = 200

distance = area

=> distance = 200m
