From laws of motion:
Where S is the distance/displacement (as you would call it) which is unknown
v = final velocity which is 0m/s (this is because the car stops)
u = initial velocity which is 36m/s (from the data given)
t = time taken for the distance to be covered and it is 6s
Substitute the values, hence:
But this is merely the distance he travelled in the 6 seconds he was trying to stop the car.
Therefore, the distance between the car and the cows = 160-108
Distance = 52m

Answer:
a)
b).
Explanation:
Given that
Boyle's law
P V = Constant ,at constant temperature
a)
Given that
We know that for PV=C
Now by putting the values
PV= 50 x 0.106
Where P is in KPa and V is in
b)
PV= C
Take ln both sides
So
lnP + lnV =lnC ( C is constant)
By differentiating
So
When P= 50 KPa
It indicates the slope of PV=C curve.
It unit is .
Or we can say that .
