<span>a = (v2 - v1)/t= acceleration formula
a = (70 - 0)/7
a = 10 km/hr/sec
-----
It's better to use as few units as possible.
10 km/hr = 10 km*1000 m/km/(1 hr*3600 sec/hr) = 25/9 m/sec
a= 25/9 m/sec/se</span>

Explanation:
When you brake all of a sudden, if you are not wearing a seat belt, your face is bound to hit against the windshield. The seat belt stops this inertia.

Explanation:
Given the following :
Distance between Ranjan and Gomez house = 9km
Start time = 6'o clock
Time he arrived at Gomes house = 7'o clock
Time used for chatting during this period = 5 minutes
Distance covered in 40minutes = 6km
Time spend for second part of the journey = (60 - (40 + 5))minutes = 15 minutes = 15/60 = 0.25 hoir
Distance covered during second part of journey = 9 - 6 = 3 km
Speed = distance / time
Speed = 3km / 0.25 hr = 12km/hr
Average speed for entire journey :
First part :
Speed = distance / time
Time = 40 minutes = (40/60) = 0.667 hour
Speed = 6km / 0.667 hour = 9km / hr
Average speed :
(First part + second part) / 2
(9km/hr + 12km/hr) / 2 = 21km/hr / 2 = 10.5 km/hr
= 10.5km/hr
