Question

Pls do the [C]............. ​

Answer 1

Answer:

u = 0 m/s

v = 5 m/s

time = 20s

By v= u + at

5 =0 + a×20

a = 1/4m/s^2

after 1 min. that is 60s

S = ut +1/2 at^2

S = 1/2 × 1/4 × (60) ^2

S = 3600/ 8

S = 450m

Hope it helps..

Answer 2

Explanation:

we can also do it by the area formula

that means the area of the velocity graph gives displacement which is equal to the distance in this case because both are in the same direction

therefore ,

by the area of the triangle

1min= 60secs

therefore

1/2 * base * height

1/2 * 60*15

= 450 m

done
