Question

A car was moving at 14 m/s after 30 s jts speed increadsed to 20m/s what is the acceleration

Answer 1

A :-) given -
u ( initial velocity ) = 14 m/s
v ( final velocity ) = 20 m/s
Time = 30 sec
Solution -
a = v - u by t
a = 20 - 14 by 30
a = 6 by 30
( cut 30 and 6 because 6 x 5 = 30 )
a = 5

.:. The acceleration is 5 m/s^2
