Distance traveled and time taken to travel that distance.
It depends on what information you have: whether you know the wave function or you know the speed and wavelength.
you can find the distance when you know your speed and the time you traveled
You use the information you have, in connection with the formulas you know that describe relationships between speed and the information you have, to derive the speed.
In that case, it would be good to know what you aregiven. It is possible that you don't have enough information.
Not enough information. If you also know an object's mass, you can use Newton's Second Law to find the acceleration. Then simply multiply acceleration x time to get the speed (assuming that the initial speed is zero).
you can not know that information
-- We can't say anything about the velocity, because we don't know anything about the horizontal motion of the ball. With the information included in the question, we can only be sure of how the vertical component of velocity behaves. -- At the maximum altitude of the ball, there's the instant where its vertical speed changes from upward to downward. At that instant, its vertical speed is zero.
In that case, it would be useful to know what you DO know. You can use the formula speed of wave = frequency x wavelength, and if you know two of the three pieces of information, you can calculate the third one. Otherwise, you don't have enough information; you may need to actually measure the wave for example.
Velocity is speed and direction
Finding the speed of a projectile, such as, a ball is simple considering you know the net force acting on the ball. Another way to go about figuring out this problem would be knowing the exact distance it traveled, most likely a parabolic trajectory excluding air drag, and knowing the time the ball was in the air; then the speed of the ball would be given as D=rt(D denoting distance, r denoting average rate/speed, and t denoting the time the ball was in the air). Back to the first method the equation used in this circumstance would be F=ma, also know as Newton's Second law of motion, and would be easiest excluding air drag. So, a person throws a 145g/0.145kg ball with a force of .5 Newtons to go about finding the speed of the ball in this equation we would use the equation F=ma-.5=.145a-a=3.45m/s2 meaning all you have to do to find the speed of the ball is multiply the value by the number of seconds after the initial thrust. Therefor, .5 seconds after the toss the ball should be-- .5s(3.45m/s2) 3.45(.5)=1.725 and m/s2/s=m/s therefor the speed is 1.725m/s after half a second. Of course after the ball strikes the ground it will be influenced by another natural force imposed by the ground which should be equal to the force that the ball initially retained. Or taking air drag into effect the force would probably no longer have an influence on the balls speed and then be effected by the law of momentum conservation. As of now all we have is a speed for the ball, 1.725m/s, we also want a velocity. To derive a velocity all the information that is needed is to know which direction the force was directed in, lets say 14o North We would now write 1.725m/s 14oN which can be written as a vector.
No, it is not possible to determine the speed of someone in space based on the information given. To calculate speed, we need to know the distance traveled and the time it took to travel that distance, and in this case, we don't have either of those values. We know that one year on the spaceship is equal to 50000 years on Earth, but that does not provide us with any information about the speed of the spaceship.
time=distance x speed. to find speed, it is speed=distance/time distance=speed x time.
