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.
How does friction apply to bowling?
when a bowling ball(reactive ball) goes down the lane, generally the first 38-41 ft are covered with oil. The other 15 ft, the backend or dry is what the ball "hooks" or Reacts off of. the coverstock of the ball expounds the oil on the ball and the fricition between the ball and lane cause the ball to "hook"
Will water in underground pipes freeze?
If the line is above the frost line. That can be 4 ft. down.
What is the size of a wind driven wave?
The size of a wind-driven wave could be anywhere from 1ft. to about 10-15 ft.
How long does it take for a bullet fired into the air to come down?

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 .
What is the equation for velocity?
Velocity = Change in position/ Change in timeVelocity is a vector quantity meaning it has direction and magnitude. Most common measurements include:meters per second (m/s)feet per second (ft/s)and miles per hour (mi/h)
How many gallons will fill a 15ft x 15ft x 8ft tank?
15 ft x 15 ft x 8 ft = 1800 cu ft = 11,211.9 Imperial gallons or 13,464.9 US gallons.15 ft x 15 ft x 8 ft = 1800 cu ft = 11,211.9 Imperial gallons or 13,464.9 US gallons.15 ft x 15 ft x 8 ft = 1800 cu ft = 11,211.9 Imperial gallons or 13,464.9 US gallons.15 ft x 15 ft x 8 ft = 1800 cu ft = 11,211.9 Imperial gallons or 13,464.9 US gallons.
How many m2 is 15 ft by 13.5 ft?

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
