Answer: v=u+at Step-by-step explanation: Initial speed u=80 km/h=80× 18/5 =22.22 m/s Final speed v=60 km/h=60× 18/5 =16.67 m/s Using v=u+at Or 16.67=22.22+α×5 ⟹ a=−1.1 m/s^2 Reply
Answer:
v=u+at
Step-by-step explanation:
Initial speed u=80 km/h=80× 18/5 =22.22 m/s
Final speed v=60 km/h=60× 18/5
=16.67 m/s
Using v=u+at
Or 16.67=22.22+α×5
⟹ a=−1.1 m/s^2
