2). use v=u+at
60-80=a5
a=-4km/hr²
=-4*5/18 m/sec
3). same formula
40*5/18= 200/18m/s
t=10*60=600sec
200/18=a*600
a=200/18*600
60-80=a5
a=-4km/hr²
=-4*5/18 m/sec
3). same formula
40*5/18= 200/18m/s
t=10*60=600sec
200/18=a*600
a=200/18*600

In question 2 there is also km/h so don't we have to convert that ?
1km/hr= 5/18 m/sec
ya so 80km/h and 60km/h
