if a bus travelling at 20m /s is subjected to steady deceleration of 5

1.	if a bus travelling at 20m /s is subjected to steady deceleration of 5m/s square how long will it take to come to rest
Answer» Answer: Initial velocity with which the bus is moving = u= 20m/s. Final velocity which it has to GAIN = v= 0m/s. Deceleration = 5 m/s^2. Applying, v = u - at => 0 = 20 - 5 ×t => 5t = 20 => t= 4s. Hence, TIME taken = 4 SECONDS

if a bus travelling at 20m /s is subjected to steady deceleration of 5m/s square how long will it take to come to rest

Answer»

Answer:

Initial velocity with which the bus is moving = u= 20m/s.

Final velocity which it has to GAIN = v= 0m/s.

Deceleration = 5 m/s^2.

Applying,

v = u - at

=> 0 = 20 - 5 ×t

=> 5t = 20

=> t= 4s.

Hence, TIME taken = 4 SECONDS
