I hope this helps you ❤️❤️

Answer 2

Required Answer :-

→Initial velocity (U) = 80 km/hr

= 80 × 5/18

= 400/18

= 22.2m/sec

→Final velocity (V) = 60 km/hr

= 60 × 5/18 = 300/18

= 16.6m/sec

→Acceleration a = (V - U) / t

=> (16.6 - 22.2)

=> -5.6/5

$= > - 1.12ms { }^{ - 2}$

Negative sign indicates that the velocity is decreasing.

$retardation = - 1.12ms {}^{ - 2}$

Heyylloo :)
