Question

A body undergoing uniform motion travels at a velocity of 20m/s. what is its velocity after 10s?

Answer 1

Answer:

20 m/s

Explanation:

In uniform motion , velocity is constant as body is covering equal distances in equal intervals of time . Even when time is infinity , the velocity is same unless a force acts on the body .

Answer 2

Answer:

hope this helped you

Explanation:

v =20m/s

u =?

t =10s

v =u+at

$(20)^{2}$ = 0+a×10

400= 10a

a =400/10

a= 40m/s

$(20)^{2}$= u+40×10

400= u+400

u=0
