On a flat, level road, a 1500-kilogram car travels around a curve having a constant radius of 45 meters. The centripetal acceleration of the car has a constant magnitude of 3.2 meters per second squared. Calculate the car's speed as it travels around the curve

Speed of the car around the circular path will be 12 m/sec

Explanation:

We have given mass of the car m = 1500 kg

Radius of the curve r = 45 m

Centripetal acceleration of the car

We have to find the speed of the car

We know that centripetal acceleration is given by , here v is car speed along the circular path and r is radius of the curve

So

v = 12 m/sec

So speed of the car around the circular path will be 12 m/sec

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
