Question

0. A car starts off from rest with a uniform
acceleration of 0.5 m s?. What will be its
velocity when it has travelled a distance of
25 m? How many seconds did it take to
cover this distance? [Ans. 5 m/s, 10 s]​

Answer 1

u=0

v= ?

s= 25m

a= 0.5 m/s²

s= ut+1/2at² = 1/2 at²

25 = 1/2 × 0.5 t²

25 ×4 = t²

t= 10 s

a×t = v-u

0.5 × 10 = v- 0

v= 5 m/s
