What is the momentum of a 21 kg bicycle traveling west a 3.0 meters per second?

Momentum = m V = (21) x (3 west) = 63 kg-m/sec west(Bold italics are vectors)


An airplane flying from New York to Los Angeles is traveling at a velocity of 1400 kph west There is a head wind with a velocity of 20 kph east What is the resultant velocity of the airplane in kph?

1380 kph west


At one p.m. a car traveling at a constant velocity of 94 km per hour toward the west is 17 km to the west of your school. Where will it be at 330?

A vehicle that is traveling at 94 km/hr travels west from 1:00 p.m. to 3:30 p.m. That's 2 and 1/2 hours of travel time at 94 km/hr. The car will travel 94 km/hr times 2 1/2 hr or 235 km in the time specified. That means the car will be that much farther west than it was at the start, which was 17 km west of a school. Add the distance from the school to the starting point of the vehicle and you'll know where the car will be at the end of the observation period. 235 km + 17 km = 252 km west of the school.


A car is traveling at a velocity of 70 km hr west to have the same velocity another car would have to travel at?

Another car would have to travel at 70 km/hr west.To have the same velocity, it must have the same speed toward the same direction.


What is the velocity if a plane traveling northwest at 610 mph?

The velocity of the plane is a vector quantity that includes both its speed and direction. In this case, the plane is traveling northwest at a speed of 610 mph. Therefore, the velocity can be described as 610 mph at an angle of 45 degrees from the north or west, depending on the reference frame used. This indicates both the speed and the direction of travel.
