Question

if a bus traveling at 40 metre per second is subjected to a steady deceleration 5 metre per second square how long will it take to come rest​

Answer 1

Answer:

Time taken by the to come to rest will be 8 seconds.

Explanation:

Initial velocity =40 m/sec

Final velocity =0 m/sec

Deceleration =-5 m/sec^2

Formula:

-a=final velocity - initial velocity / time taken

time = 0 - 40 /-5

time = -40/-5

time = 8 sec.
