If a car has a velocity of 40 km/h west and then comes to a stop in 5 s, what is its acceleration in m/s2?

1 answer:

6 0

acceleration = change in velocity /change in time

convert 40km to meter then divide it with 5

Initial velocity (Vi) = 25 m/s

acceleration (a) = $-4 m/s^{2}$

time interval (t) = 5 sec

let us assume that final velocity after 5 sec be Vf

As acceleration is constant, we can apply the the equation of motion with constant acceleration i.e. $V_{f} = V_{i} + at$

Hence, $V_{f} = 25 +(-4)(5) = 25 -20 = 5 m/s$

so, the velocity of bicyclist will be 5 m/s after 5 sec
