The tires of a car make 75 revolutions as the car reduces its speed uniformly from 95 km/hr to 55 km. hr. the tires have a diameter of 0.80 m. (a) what was the angular acceleration of the tires? (b) if the car continues to decelerate at this rate, how much more time is required for it to stop and (c) how far does it go?

a)

b) t = 12.43 sec

c) s = 95 m

Step by Step Solution :

Given :

Number of revolution (N) = 75

Diameter = 0.80 m

Calculation :

We know that,

a) Angular Acceleration is ,

b) Time required by the car to stop

c) The distance covered by the car

--- (1)

From equation (1)

s = 95 m (Approx)

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.
