1. An 800 kg car travels around the edge of a circular track of radius 400 m. At one point, the car accelerates around the track, increasing its speed from 40 m/s to 60 m/s over the course of 5 s. At the instant that the car reaches 50 m/s find (a) its angular velocity (b) its radial acceleration, (c) the centripetal force acting on the car, (d) the tangential acceleration of the car, and (e) the magnitude of the...
A car with initial tangential speed of 10m/s accelerates on a circular track with radius of 100 m and with angular acceleration of 2 rad/s^2. How long it takes for the car to have its centripetal acceleration of 9 m/s^2? This is the question in verbatim.
A race car travels with a constant tangential speed of 81.3 m/s around a circular track of radius 678 m. Find the magnitude of the total acceleration.
Suppose you are driving a car in a counterclockwise direction on a circular road whose radius is r 28 m/s (about 63 mi/h) 385 m (see the figure). You look at the speedometer and it reads a steady T(decreasing) (a) Constant angular speed (b) Decreasing angular speed Concepts (i) Does an object traveling at a constant tangential speed (for example, vT= 28 m/s) along a circular path have an acceleration? Yes No (ii) Is there a tangential acceleration aT when...
A car starts from rest and moves around a circular track of radius 32.0 m. Its speed increases at the constant rate of 0.550 m/s2. (a) What is the magnitude of its net linear acceleration 19.0 s later? (b) What angle does this net acceleration vector make with the car's velocity at this time? Question 6 A car starts from rest and moves around a circular track of radius 32.0 m. Its speed increases at the constant rate of 0.550...
1 and 2 Question 1 2 pts A car of mass 1.8 tons moves with a speed of 34 m/s on a circular track of radius 90 m. What is the magnitude of its angular momentum (in Mkg x m2/s) relative to the center of the race track? (one ton 1000 kg, Mkg Mega-kg) Question 2 2 pts A puck on a frictionless air hockey table has a mass of 2.1 kg and is attached to a cord passing through...
2. A car is driving at constant angular speed along a 20 m radius circular track. The car completes one revolution of the track in 10 seconds. Calculate: (i) The (tangent) speed of the car. 12.6 m/s (ii) The angular speed of the car. 0.63 1/s or 0.63 rad/s (iii) The centripetal acceleration of the car. 7.9 m/s2 (iv) The RPM (i.e. revolutions per minute) of the car. 6 RPM THE ANSWERS ARE IN BOLD, COULD YOU PLEASE SHOW THE...
P6 A car travels around a circular track at constant speed, as shown. It is observed that the car takes 15.71 seconds to go from point A to point B along the track (exactly a quarter circle). An accelerometer mounted on the car shows that its acceleration has a constant magnitude of 7.0 m/s2. Please answer each of the following questions. For answers that require vectors, refer to the instant shown in the figure. a) What is the radius of...
