A toy car travels around a flat circular track, at a constant speed, one full revolution every 6 seconds. ​Show your work​ and​ include units​ in your answers. The radius of the track is 1.1 meters. The mass of the toy car is 0.12 kg. T = 6 s, r = 1.1 m, m = 0.12 kg a) How fast is the car traveling? (What is it’s tangential velocity?) aaa bonus) What is the car’s angular velocity? b) In which direction is the car accelerating? c) What is the car’s centripetal acceleration? ccc bonus) What is the car’s angular acceleration? d) What is the magnitude of the centripetal force acting on the car? e) What is the frequency of the car around the track?

grav potential energy

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.  

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
