It is friction that provides the force for a car to accelerate, so for high-performance cars the factor that limits acceleration isn't the engine; it's the tires. you may want to review ( pages 138 - 142) . part a for typical rubber-on-concrete friction, what is the shortest time in which a car could accelerate from 0 to 60 mph? suppose that μs=1.00 and μk=0.80.

Let the acceleration of the system is a and the time to reach 60 mph is t, so 

ax = (μs - μr) * g 
ax = (1.00-0.80) (9.8 m/s2) = 1.96 m/s2 
Then I used acceleration in this equation: 
vf = vi + ax * t 
60 mph = 0 mph + (1.96 m/s2) t 
t = (60 mph/1.96 m/s2)(0.447 m/s / 1 mph) 
t = 13.68 s

when earth is in rotational motion around the sun,it displaces from its place.

when a ball is placed on an inclined surface it does both the rotational and circular motion.
