Question

1) u=14m/s
v= 10m/s
t = 2 s
a=?​

Answer 1

Answer:

v = u + a t

10 = 14 + a x 2

10-14 =2a

-4/2=a

a = -2

Retardation is occuring....

Answer 2

Answer:

-2m/s^2

Explanation:

v=u+at

or, 10=14+a.2

or, 2a= -4

or, a = -2

Actually the subject is slowing down in 2m/s^2 reverse acceleration.
