GM hat is the difference in orbital velocity between Saturn's two coorbital satellites if the semimajor axes of their orbits are 151,400 km and 151,500 km? (Hint: Use the formula for orbital velocity, V.

To visit your favorite ice cream shop, you must travel 470mwest on Main Street and then 980msouth on Division Street. Suppose you take 46sto complete the 470-mdisplacement and 73sto complete the 980-mdisplacement.What is the direction of your average velocity during this 119-second period of time?Express your answer to two significant figures.

Bob has just finished climbing a sheer cliff above a level beach and wants to figure out how high he climbed. All he has to use is a baseball, a stopwatch, and a friend on the ground below with a long measuring tape. Bob is a pitcher and knows that the fastest he can throw the ball is about ?0=34.1 m/s.v0=34.1 m/s. Bob starts the stopwatch as he throws the ball, with no way to measure the ball's initial trajectory, and watches carefully. The ball rises and then falls, and after ?1=0.910 st1=0.910 s the ball is once again level with Bob. Bob cannot see well enough to time when the ball hits the ground. Bob's friend then measures that the ball hit the ground ?=123 mx=123 m from the base of the cliff. How high above the beach was the ball when it was thrown?

4. An astronaut is said to have tried to get out of a traffic violation for running a red light ( 650. nm) by telling the judge that the light appeared green ( 540. nm) to her as she passed by in her high-powered transport. If this is true, how fast was the astronaut going?

Both the slope and percentage calculations please

Two automobiles are 150 kilometers apart and traveling toward each other. One automobile is moving at 35 km/h and the other is moving at 40 km/h. In how many hours will they meet? A) 2.5 h B) 2.0 h C) 1.75 h D) 1.5 h F) 1.25 h

Omar swims across a river at a velocity of 2.50 m/s [30o N of E] with respect to the water. The current is 5.4 m/s [E]. She crosses the river in 425 seconds. Determine the width of the river.

ANSWER QUICK! Ive read the honor code and it says that their a question can have up to 3 subparts (i.e. part a, b, and c). So please answer all questions. A train is travelling east along a straight run of track at 66 km/hr. Inside, two siblings 2.2 m apart are playing catch directly across the aisle. The kid wearing a PJ Harvey T-shirt throws the ball horizontally north. The ball crosses the train and is caught 1.2 s later by their little sibling. (Ignore any effects of gravity or friction.) Find the magnitude of the ball's velocity in m/s from the little brother's point of view. What is the magnitude of the velocity (in m/s) of the ball as seen by someone standing still outside the train? What is the angle (in degree) that a stationary observer would say the ball makes during the throw, relative to the direction of the train?

The distance from the Earth to the moon is 239,000 miles. The distance from the Earth to the moon is 385000 km. Given that light travels at 3.00 × 10⁸ m/s how many minutes does it take for light to travel to the moon?
