Question

a certain car has an acceleration of 2.4m/s2. assume that is acceleration remains constant. starting from rest. how long does the car require to reach velocity of 90km/h? how far does it travel while reaching that velocity?

Answer 1

Explanation:

v=u+at

90km/hr=25 m/s

25=0+2.4t

t= 10.4 sec

We know s= ut+0.5at²

s= 0+0.5×2.4×10.4×10.4= 129.79 m

approximately 130m
