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
Answer:
25%
Step-by-step explanation:
George is 33% (
%) richer than Pete. Let Pete's percentage of wealth be 100%.
Thus George percentage of wealth = 100% + %
= %
= 133%
Pete's percent poorer than George can be determined by;
= ÷
× 100
= ×
×100
= 0.25 × 100
= 25%
Pete is 25% poorer than George.
