Answer 1

4km/hr is the answer okay okay

Answer 2

Given :-

A car speed increase from 40 km/hr to 60 km/hr in 5 sec

To Find :-

acceleration

Solution :-

converting kn/h into m/s

40 × 5/18 = 200/18 = 11.11 m/s

60 × 5/18 = 300/18 = 16.66 m/s

Now

a = v - u/t

a = 16.66 - 11.11/5

a = 5.5/5

a = 1.1 m/s²
