Hey mate!!
✴ PHYSICS ✴
__________________
Initial velocity (u) = 80km/hr
=> 80 × 5/18
=> 400/18 ...m/s
Final velocity (v) = 50km/hr
=> 50 × 5/18
=> 250/18 m/s
Time taken (t) = 4 sec.
acceleration (a) = ?
We know that ,
v = u + at
=> a = v - u/t
Refer to the attachment above for your answer..
✴Thanks for the question!!✴

HEYA MATE, HERE IS UR ANSWER __________________________
Initial velocity (u)=80km/hr
= 80 ×5/18
= 400/18m/sec
Final velocity(v) =50km/hr
= 50×5/18
=250/18m/sec
Time(t)=4sec
acceleration (a)=V-u/t
a=250/18-400/18/4
a=-150/18/4
a=-150/72
a=-2.08m/sec^2.
