Answer:
20000 pounds
Explanation:
Generally 1 gallon of fuel burnt gives of 20 pounds of CO₂
Difference in the gallons of fuel burnt
The 20 mpg car burns 1000 gallons of fuel more than the 30 mpg car
The amount of CO₂ would be
The fewer pounds that the 30 mpg car would release is 20000 pounds
The tangential velocity of the car is 124.5 m/s
Explanation:
The centripetal acceleration of an object in uniform circular motion is given by:
where
a is the acceleration
v is the tangential velocity
r is the radius of the circle
For the car in this problem, we have:
is the centripetal acceleration
r = 155 m is the radius of the turn
Solving for v, we find the tangential velocity of the car:
