A race car goes around a level, circular track with a diameter of 1.00 km at a constant speed of 89 km/h. What is the car's centripetal acceleration in m/s2?
5. A race car is driven around a circular track at a constant 150 miles per hour. If the diameter of the track is 1/2 mile, what is the angular speed of the car? Express your answer in revolutions per hour (which is equivalent to laps per hour).
A race car enters the circular portion of a track that has a radius of 63 m. When the car enters the curve at point P, it is traveling with a speed of 120 km/h that is increasing at 5 m/s2. Three seconds later, determine the xand y components of velocity and acceleration of the car. 120 km/h
A race car rounds one end of a speedway. This end of the track is a turn with a radius r of approximately 187 ft. If the track is assumed to be completely flat and the race car is traveling at a constant 67.00 mi/h around the turn, what is the race car's centripetal (radial) acceleration ac? 1) ac= ft/s2 Convert this result to SI units. 2) ac= m/s2 3) What is the force responsible for the centripetal acceleration in...
A race car enters the circular portion of a track that has a
radius of 61m. When the car enters the curve at point P, it is

Express in km/h iii) If the fastest lap time is 2 min and 20 sec, what is the average speed for this lap? Express your answers in m/s. iv)...
Uniform linear motion 5. (10 pts) A car moves with a constant velocity along a straight road. Its position is xi 0 m atti-0 and is x2 30 m at t2 3s a. what is the car's velocity at t = 1 s? b. What is the car's displacement between t 1.5 s and t2.5 s? 6. (15 pts) In an 8-km race, one runner runs at a steady 12 km/h and another runs at 14.5 km/hr. If they start...
A race car travels northward on a straight, level track at a constant speed, traveling 0.937 km in 12.1 sec. The return trip over the same track is made in 26 sec. (a) What is the average velocity of the car for the FIRST leg of the trip? (b) What is the average velocity of the car for the SECOND leg of the trip? (c) What is the average velocity of the car for the WHOLE trip? Part Answer Units...
