Question

Can anyone send me full solution of this Ans
the right Ans I'll mare as brainlest​

Answer 1

answer is 1/3m/s2

Explanation:

Time= 10 sec velocity= 12km/h = 12×5/18 m/

acceleration using of equation of motion

V=u+at

12×5/18 =0+a×10

Answer 2

Explanation:

initial velocity (u) = 0 km/h = 0m/s

( bcz starts from rest)

final velocity (v) = 90 km/h (given)

= 90× 1000m ÷ 3600s

=. 90000/ 3600

= 100/4

= 25m*2/s

time=10s

let the required acceleration be (a)

by using v= u+at

a= v-u ÷ t

a= 25 -0 ÷ 10

a =. 25/10

= 2.5 m/s *2 ans
