49. A car with its wheels locked rests on a flatbed of a tow truck. The flatbed's angle with the horizontal is slowly increased.
When the angle becomes 40°, the car starts to slide. Deter-
mine the coefficient of static friction between the flatbed and
the car's tires.

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

The correct choice is c
