acceleration = change in velocity /dt
A = dv / dt
dv= 80 - 60
dv= 20
=20 × 5 / 18
= 50 /9 m/s
time = 5 ×60
time = 300 sec
acceration = 50 / 9 × 300
A = 5 / 270
A = 0.018 m/s²
A = dv / dt
dv= 80 - 60
dv= 20
=20 × 5 / 18
= 50 /9 m/s
time = 5 ×60
time = 300 sec
acceration = 50 / 9 × 300
A = 5 / 270
A = 0.018 m/s²

initial speed(velocity) u=80km/hr =288m/s
final speed(velocity) v =60 km /hr = 216m/s
time = 5min = 300 sec
acceleration =v-u/t
=216 -288/300
=-0.24m/s^2
