Explanation:
An athlete is running along a straight path with a constant velocity of 10m/s. Draw a velocity-time graph for athlete's motion. How much distance does he cover in 20 seconds?
We can apply here formula for Distance calculation
Distance = ut + (1/2)at²
where u = initial velocity 10 m/s
acceleration a = 0 ( as constant velocity)
time = t = 20 sec
=> Distance = 10(20) + (1/2)(0)(20)²
=> Distance = 200 + 0 m
=> Distance = 200 m
200 m distance covered in 20 sec
Answer:
He covers 200 meters in 20 seconds.
Explanation:
As body is running along the straight line so here the acceleration will be zero i.e. a= 0. Velocity is given which is 10m/s and time is also given which is 20 second.
We know the formula that distance is equal to velocity multiplied with time
Distance = Velocity x Time = 10 x 20 = 200 meter.
Distance traveled by 20 second will be 200 meter which is represented in graph as area under curve.
