Introduction:
Velocity
In physics velocity is a rate of motion and direction of motion with a vector measurement. Velocity is also defined as the rate of change of direction of an object. Speed of the motion is the scalar magnitude of the motion. The velocity is measured using the unit meters per second. Velocity is measured as m/s in SI unit. Since velocity depends on the motion and direction the practice of velocity problems depends on it. Acceleration, inertia and speed are some of the related terms to practice velocity problems. Here we are going to practice some velocity problems. Having problem with Formula for Instantaneous Velocity keep reading my upcoming posts, i will try to help you.
Practice Velocity problems
1.What is the speed of a train that travels 2000 meters in 10 seconds?
Solution
Distance = 2000 meters
Time = 10 seconds
Velocity = distance by time taken
= 2000 / 10
= 200 m/s
2. You are on a trip of 400 km with an average speed of 80 km/hr. how long will your trip be in hours to complete the entire distance?
Solution
Total distance to be covered = 400 km
Average Speed (velocity) = 80 km /hr
Time taken = Distance / speed
= 400 / 80
= 5 hours
So it will take 5 hours to complete the distance with the speed of 80 km/hr.
3. What is the time taken by a jet to travel a distance of 720 km at a rate of 120 m/s?
Solution
Distance = 720 km/s
Rate = 120 m /s
Here the distance is given in km. so first we convert the total distance into meter.
We know that 1 km = 1000 m
So 720 km = 720 * 1000
= 720000 m
Time taken = distance / rate
= 720000/ 120
= 6000 seconds
