I tried to send the picture vertically, but the bottom part was cut off. So I turned it horizontally. Please understand that.
Answer:
There are 3 ways
Step-by-step explanation:
The formula for a sector's area is:
1. A = (sector angle / 360 ) * (pi *r2)
2. A = (sector angle / (2*pi)) * (pi * r2)
3. A = (fraction of the circle) * (pi * r2)
Answer:
Deceleration =
units/sec^2
Step-by-step explanation:
Given that a car is traveling at when the driver sees an accident m ahead and slams on the brakes.
i.e. if he is coming with speed v units/sec say, he has to make his velocity 0.
Distance travelled = m units
Initial velocity = v
Final velocity =0
Use the third formula as

So he has to apply an acceleration of
units/sec^2 to stop the car in time to avoid a pile up.
Deceleration =
units/sec^2
