Question

A bus decrease its speed from 90kmh to 60kmh in 15 sec .find acceleration of bus?


solve it.........by the time........​

Answer 1

Answer:

-1.6

Explanation:

a=v-u/t

a= (600/36-900/36)/5

a= -1.6m/s^2

Answer 2

Answer:

it's a negative acceleration, which is called declaration

negative acceleration = (final velocity - initial velocity)/ time

=( ( 90-60) km/h)/ 15 sec

= ((30 ×5)/18) m/sec/ 15 sec

= 30×5/18 ×15= 10/18 m/sec^2

here is ur answer.
