A horse races once a round a circular track in a time of 118 s, with a speed of 17 m/s. What is the radius of the track

A car drives around a circular track of diameter 156 m at a constant speed of 33.0 m/s. During the time it takes the car to travel 102 degrees around, what is the magnitude of the car s average acceleration?      13.96 m/s^2     6.98 m/s^2     12.19 m/s^2     0 m/s^2 CANNOT USE CENTRIPITAL MOTION EQUATION, must calculate average acceleration

You built a pinball machine that has a banked circular track with radius 0.34 m. The ball shooter launches the ball directly into this circular track before the ball enters into the game. You fire pin balls at a constant speed into the track and adjust the banking angle until it works. The banking angle is 21 degrees. Assume your pin ball machine is on a horizontal plane, how fast is the ball launched into the track, in m/s? Hint: I have a video on this problem about swing pendulum but the results are very similar, except a string length was given instead of path radius and tension was present instead of normal force. Assume friction is negligible.

A runner travels on a circular path with velocity equation (t) = 0.06t2 + 0.15t, starting from rest. It took him 3.25 seconds to finish the first 5-meter run. Find the radius-of-curvature of the circular track if he achieves a total acceleration of 12 m/s2 at the time he covered a distance of 28 meters.

We know that the moon Callisto revolves around Jupiter during a period of 17.0 days.17.0 days. The average distance from the center of Jupiter to the center of Callisto is 1.95×109 m.1.95×109 m. What is the acceleration ?a of Callisto due to its motion around Jupiter?

During their field trip to the amusement park, Eli and Frank took a rider on the Whirligig. The Whirligig ride consists of long swings which spin in a circle at relatively high speeds. They estimate that the riders travel through a circle with a radius of 6.5 m and make one turn every 5.8 seconds. Determine the speed of the riders on the Whirligig.

A speed skater increases his speed from 10m/s to 12.5m/s over a period of 3s while coming out of a curve of 20m radius. What is the magnitude of the resultant acceleration as he leaves the curve?

You and a friend ride your bikes to a restaurant across town. Both of you start at the same instant from your house, you riding 10 m/s and your friend riding 12 m/s. During the trip your friend has a flat tire and that takes him 8 minutes to fix. He then continues the trip at the same speed of 12 m/s. If the distance to the restaurant is 10 km, who gets there first?

The car travels around the portion of a circular track having a radius of r = 500 ft such that when it is at point A it has a velocity of 2 ft/s, which is increasing at the rate ofa = 0.002t in ft/s, where t is in seconds. Determine the magnitudes of its velocity and acceleration when it has travelled three-fourths the way around the track. O v = 36.83 ft s^-1 ; a = 2.74 ft s^-2 O v = 28.11 ft s^-1 ; a = 1.61 ft s^-2 O v = 17.71 ft s^-1 ; a = 0.68 ft s^-2 O None of the choices
