Define the term velocity. what are its various units Is it a scalar or vector quantity?
Velocity is a vector quantity, meaning that it has both a magnitude and a direction. Mass, on the other hand, is a scalar quantity; it has a magnitude only. Velocity is measured in units of distance divided by time; for example, meters per second or miles per hour.
Velocities in opposite directions combine by what?
Vector addition of velocities would be if something like you were on an escalator, which is going down, and you tried to run up the escalator. So if the escalator is moving down at a rate of 5 ft/sec and you run up at 13 ft/sec (relative to the escalator) then the net velocity relative to the Earth is 8 ft/sec up. So you just subtract, because the two vectors are in the same line. OK so really the direction is at an angle (rather than 'up'). The larger velocity direction will determine the net direction. If you were walking up the escalator at 3 ft/sec (relative to the escalator), then your net velocity is 2 ft/sec down.
What is the numerical ratio of a velocity to speed of an object?
Velocity is an object's Speed + Direction. For example, a cannon ball fired up at 45o to the ground may have a speed of 1000 ft/sec. However, its forward Velocity is:(1000 ft/sec) x (Sine 45o) = (1000 ft/sec) x (.707)= 707 ft/secSo, the ratio of the horizontal Velocity to the instantaneous Speed of the object is the SINE value of the angle of motion relative to the Horizontal axis.But you have to remember that there is a Vertical component of the object's Speed as well. In this case, the ratio is the COSINE 45o , which happens to be .707 as well. So the ball is going forward at 707 ft/sec, and upward at 707 ft/sec. at the same time.
Two forces act on the same object One force is pushing due east with a force of 6 newtons and the other is pushing due north at 8 newtons What is the resulting force?
The magnitude of the resulting force is 10 N. Because the forces are perpendicular, we can use Pythagoras' theorem:FT = SQRT ( F12 + F22 ) where:FT is the total force;F1 is the first force; andF2 is the second forceUsing this equation, we get:FT = SQRT ( 62 + 82 )FT = SQRT ( 36 + 64 )FT = SQRT ( 100 )FT = 10
How do you keep a egg from breaking if you drop it from 15 ft?
You can prevent an egg from breaking when dropped from 15 ft by wrapping it in a cushioning material, such as bubble wrap or foam, or placing it in a container filled with a shock-absorbing substance like cotton balls or rice. These materials can absorb the impact and reduce the force transmitted to the egg when it hits the ground.
How many sq ft in 15 ft x 15 ft?

How do you calculate the velocity and acceleration of falling objects?
As usual when we talk about falling objects, we have to ignore air resistance,because its effects depend on the size, shape, and composition of the objectthat's falling, as well as the temperature, pressure, humidity, and wind-speedof the local air, and we have none of that information. So we must simply treatthe whole subject as if the only effects on the falling object are those that arethe result of gravity.Velocity:-- The direction of the velocity vector is down.-- The magnitude of the velocity vector (called "speed") is(initial downward speed when dropped or tossed) plus (acceleration x time spent falling).Acceleration:-- Direction of the acceleration vector is down.-- Magnitude of the acceleration vector depends on what planet you're on or near,but is always the same as long as you stay there, and doesn't need to be calculated.In the case of Earth, it's 9.8 meters (32.2 ft) per second2 .
How many gallons will fill a 15ft x 15ft x 8ft tank?

How many linear feet around 15 ft round pool?
If the 15 ft is the distance around the edge, then:Distance_round_edge = 15 ft If the 15 ft is the diameter of the round pool, then:Distance_round_edge = π x diameter = π x 15 ft= 15π ft≈ 47.12 ftIf the 15 ft is the radius of the round pool, then:Distance_round_edge = 2 x π x radius = 2 x π x 15 ft= 30π ft≈ 94.25 ft
