Question

12) 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?​

Answer 1

Answer:

s =ut + 1/2 at^2

v= 10m/s

u= 0

a= v-u/t

a=10-0/20=1/2 m/s^2

s= 0+ 1/2 ×1/2(20)^2

s= 0+ 1/4×400

s= 100m
