1.	A car increases its speed from 60km/h to 70km/h in 10 second. It's acceleration is
Answer» Answer: INITIAL velocity = u = 20km/hr = 20 x 5/18 = 5.56 m/s Final velocity = V = 50 km/hr = 50 x 5/18 = 13.89 m/s Time = t = 10 sec Acceleration = a a = (v- u) / t = (13.89 - 5.56) / 10 = 0.833 m/s² Step-by-step explanation:

Answer»

Answer:

INITIAL velocity = u = 20km/hr = 20 x 5/18 = 5.56 m/s

Final velocity = V = 50 km/hr = 50 x 5/18 = 13.89 m/s

Time = t = 10 sec

Acceleration = a

a = (v- u) / t

= (13.89 - 5.56) / 10

= 0.833 m/s²

Step-by-step explanation:
