11. A mouse and a rat are at opposite ends of a horizontal bar whose length is 0.8 m and which can rotate about a point at its center. The mass of the mouse is 200 grams and the mass of the rat is 500 grams. The rat is let go and the rod rotates into a vertical position. What is the velocity of the rat when it is at its lowest position? 2 (a) 2.5 m/s (b) 4.3 m/s (c) 1.8 m/s (d) 3.1 m/s

You're out in space, on a rotating wheel-shaped space station of radius 1426 m. You feel planted firmly on the floor due to artificial gravity. The gravity you experience is Earth-normal, that is, g = 9.81 m/s^2. How fast is the space station rotating in order to produce this much artificial gravity? Express your answer in revolutions per minute (rpm). 0.083 rpm 118.3 rpm 0.554 rpm 0.792 rpm
3. A satellite is launched from the surface of the earth at the initial speed of 8 km/s. How high will it go before it stops and starts falling back to the earth?
A child is standing on a merry-go-round (u - 16) with a radius of 2 meters. What is the fastest that can he be spun while only using the friction from his feet to stay on? 157 mis 244 m/s 3.14 m/s 177 ms
A thread is wrapped around a cylindrical spool, of radius R = 2.0 cm, whose central axis is fixed on a support. Somebody’s hand pulls the thread off the spool. This causes the spool to rotate. The acceleration of the person’s hand is constant. Starting from rest, it takes 10 seconds for 5.0 meters of thread to be pulled off. What is the angular speed of the spool at time t = 2.0 s?
An angular velocity of 10 rad/s is how many revolutions per minute (RPM)? Which is the answer ? 0.535 RPM 6.28 RMP 27.2 RMP 377 RMP 95.5 RMP
The bus's wheels have a radius 26 cm. The bus starts at rest and accelerates at a constant speed until it reaches an angular speed of 10.4 rev/s. During this period, the bus moved 100 m. How many revolutions does the wheel go through?
A Ferris wheel has a radius of 30 m and its centre is 32 m above the ground. It rotates once every 48 s. Ethan gets on the Feris wheel at the lowest point and then the wheel starts to rotate. The amount of time it takes Ethan to reach 38 m above the ground for the first time, to the nearest tenth of a second, is S. Your answer
