An engineer is designing a new on-ramp for a highway. because of space limitations, the on-ramp can have a radius no larger than 40 meters. they are planning to use asphalt, which they know when wet has a coefficient of static friction of around 0.25. the smallest car that they anticipate will be taking the on-ramp is 1000 kg (a prius) and the largest is about 9000 kg (a mining truck). the on-ramp is not banked and we assume that the vehicle will travel at a constant speed.
a. what kind of acceleration will the car experience as it travels through the on-ramp?
b. calculate the maximum speed that each of the vehicles can take on the on-ramp. box your answers.
c. which of the two vehicles will have the easier time taking the on-ramp? (use the language of physics.)
d. what angular speed will the vehicles have as they travel on the on-ramp?
e. explain why banking the track makes it easier to drive through the on-ramp at higher speed. (use the language of physics.)
