A racecar, traveling at constant speed, makes one lap around acircular track of radius r in a time t. Note: The circumference of a circle is given by C = 2πr. when the car has traveled 3/4 around the track, what is the magnitude of its displacement from the starting point? Please provide calculations.
A jogger jogs around a circular track with a diameter of 225 m in 15 minutes. What was the jogger's average speed in m/s?___ m/s
a circular test track for cars has a circumference of 2.3 km. A car teavels around the track from the southernmost point to the nothernmost point. Part A: What distance does the car travel? Part B: What is the car’s displacement from its original position?
A jogger runs around a circular track of 30 m radius, as shown in the figure. She runs at constant speed in a clockwise direction for a few minutes. She completes a round in 40 s. Using N, S, E, W, cw, or ccw for the direction, compare the directions and magnitudes of her linear velocity, linear acceleration, angular velocity and angular acceleration at A, B and C
A runner is training for an upcoming marathon by running around a 112-m-diameter circular track at constant speed. Let a coordinate system have its origin at the center of the circle with the x-axis pointing east and the y-axis north. The runner starts at (x, y) = (56 m, 0 m) and runs 2.5 times around the track in a clockwise direction. What is the magnitude of his displacement vector? ............. Whar is the direction of his displacement vector? West...
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...

A 1500-kg car drives at 30 m/s around a flat circular track 300 m in diameter. What are the magnitude and direction of the net force on the car? Sort the following quantities as known, to find, or unneeded. Let m and v be the mass and speed of the car, respectively; μs is the coefficient of static friction, r is the radius of the circular path, n is the magnitude of the normal force acting on the car, and...
A 1500-\rm kg car drives at 30 \rm m/s around a flat circular track 300 \rm m in diameter. What are the magnitude and direction of the net force on the car? 9000N Since the net force is equivalent to the force of static friction, your answer to Part D is the magnitude f_s. Based on this value, what is the minimum coefficient mu_s of static friction between the road and the car?
