Given that,
A car is moving on a straight road with uniform acceleration.
Time = 0, 10, 20, 30, 40, 50
Speed = 5, 10, 15, 20, 25, 30
The slope of graph AB is called acceleration.
We need to calculate the acceleration of car
Using graph,
Put the value into the formula
(II). We need to calculate the distance travelled by the car in 50 sec
Using graph
Distance traveled by truck = Area of trapezium OABD
Put the value into the formula
×(5+30)×50
D= 875\ mD=875 m
Hence, (I) The acceleration of the car is 0.5 m/s²
(II). The distance travelled by the car in 50 sec is 875 m
