A car sits at rest at the starting line of a circular racetrack. It begins to accelerate at a constant rate (that 15, a constant angular acceleration) as it makes Its way halfway around the track. It then decelerates at the same constant rate during the second halt of the lap. It completes the entire lap in a time of 28.5 seconds. Also, the radius of the racetrack is 42.0 m. What is the car's top speed?A) 25.6 m/SB) 44.1 m/SC) 18.5 m/sD) 35.1 m/s
H6. A skier/snowboarder starts at rest at the top of a snowy (friction-free) hill with height h1. After the bottom of this hill there is a small “jump” hill. The top of the jump has height h2 and a curvature of radius R. What is the minimum height of the starting hill, h1min, so that the skier/snowboarder jumps or “catches air” at the top of hill 2? Solve for h1min in terms of h2, R, and g. Hint: if the skier/snowboarder jumps, he/she/they loose contact with the snowy ground.
The hammer throw was one of the earliest Olympic events. In this event, a heavy ball attached to a chain is swung several times in a circular path until it is released. The winning athlete is the one who throws the ball the greatest distance. The last complete rotation of 2016 Olympic champion Anita Włodarczyk’s final turn took only 0.43 s. The radius of the ball’s path, including her extended arms, was 2.1 m.a. What was the frequency of this rotation?b. What was the speed of the ball?c. What was the ball’s acceleration, in units of g?
A dirt bike is traveling at a constant speed v when it happens upon a circular hill of radius r = 410 m. The driver and dirt bike together have mass m = 136 kg. a.) What speed in m/s does the dirt bike have if the driver feels weightlessness (i.e., has an apparent weight of zero) at the top of the hill? b.) If the driver is traveling at the speed above and happens upon a hill with a radiues 2r, what is the apparent weight of both the driver and the dirt bike in Newtons at the top of the hill?

A ball having a mass of 2.27 kg is swinging at the end of a cord in a vertical circle of radius 0.6 m at 2 rev/s. What is the tension in the cord when the ball is a. at the level of the center? b. At the bottom of the vertical circle?
3. A new discovered asteroid were observed by astrophysicist. It is said to be moving along a circular path of diameter 600 km. If it is revolving with an angular velocity of (3t2) rad/s, where t is in seconds, find the magnitude of the asteroid's velocity and acceleration when 0 = 30°. Note that 0 = 0° when t=0.
Is it possible for an object moving around a circular path to have both centripetal and tangential acceleration? No, because then the path would not be a circle. A (B Yes, this is possible if the speed is constant. No, an object can only have one or the other at any given time. Yes, this is possible if the speed is changing. D
