Question

A body moves from rest with a uniform acceleration 5 ms-2. After 10 s what will be its velocity?
(i) 5 ms-1
(ii) 25 ms-1
(iii) 20 ms-1
(iv) 50 ms-1
please answer me fast​

Answer 1

Answer:

Answer is 50 ms^-1 (iv)

Explanation:

Given, u = 0

a = 5 ms^-2

t = 10s

Now, v = ?

v = u + at

v = 0 + 5(10)

v = 50ms^-1

Hope it helps.....

Answer 2

Answer:

50m/s .

acceleration = change in velocity/time

so v( final) - v(initial)/ time= acc

let v final = V

5= V-0/10

5=V/10

V= 50m/s
