I'm unsure of what equations to use for this certain questions. I'd very much apreciated if anyone could tell me which equation is to be used for each individual problem. This is also a study review for an exam that's coming up very soon. 1. A bullet traveling 8.0 x 10^2 10^2 m/s horizontall hits a target 180 m away. How far does the bullet fall before it hits the target? 2. A student threw a ball herizontally out of a window 8.0 m above the ground. It was caught by another student who was 10.0 m away. What was the initial velocity of the ball? 3. A baseball was hit at 45 m/s at an angel of 45(degrees) above the horizontal. a)How long did it remain in the air? b)How far did it travel horizontally? 4. A camper dives from the edge of a swimming pol at water level with a speed of 8.0 m/s at an angle of 30.0(degrees above the horizontal. a) How long is the diver in the air? b) How high does the diver go? c) How far out in the pool does the diver land? 5. An amusement park ride consists of turntable of 2.0 m radius turning at .70 rev/s about a vertical axis. If a 70.0 kg child sits at the outer edge of the turntable, what force is necessary to keep the child from sliding off? 6.A 90.0-kg person is spinning around on the equator of planet X, which is rotating at 3.2 x 10^3 km/h. The centripetal force holding the person in place is 6.0 N. What is the radius of planet X? 7. A satellite orbits a planet at 4.0 x 10^3 m/s, and the acceleration of gravity on the satellite is .58 m/s^2. What is the diameter of the orbit? 8. What is the period of a pendulum 3.0 m long? 9. On earth the length of a pendulum with a period is 1.0 s is .25 m. What is the length of the pendulum with a period of 1.0 s on the moon, where the acceleration of gravity is 1/6 that of the earth? Thank you.
