Worksheet: Speed and Velocity
In this worksheet, we will practice differentiating between velocity and speed and solving problems involving average velocity and average speed.
If a train is moving at 315 km/h and a car is moving at 750 m/min, which of them has a speed greater than 50 m/s?
- Athe train
- Bboth of them
- Cthe car
- Dnone of them
A man sprints 100 meters in 11 seconds. Which of the following is most likely to be his top speed?
- A10 m/s
- B10 mph
- C10 m/min
- D10 km/s
- E10 km/h
A train of length 110 m moving at 180 km/h passed another train of length 190 m. Determine how long it took train to completely pass train , given that train is at rest.
Express 119.7 km/h in meters per second.
Express 36 m/min in centimeters per second.
A car moves with a velocity of 20 m/s towards east for 30 seconds. Then, it stops for 30 seconds. Finally, it moves with a velocity of 10 m/s towards west for 20 seconds. The average speed of the car during the whole trip is m/s.
The distance between two warplanes is 30 km, and they are flying at the same speed. If the plane at the back fires a missile with a speed of 450 km/h, then the missile will hit the plane at the front after minutes.
If a car moves with a uniform velocity of magnitude 72 km/h for 45 min, then the distance covered during this period of time measured in kilometers is .
If a plane moves with a velocity of 200 km/h due north for three hours, then with a velocity of 150 km/h due west for a distance of 300 km, then the average speed of the whole journey is km/h.
A car moves a distance of 60 km with a uniform speed of 60 km/h; then, it moves in the same direction for 100 km with speed . If the average speed of the whole trip is 80 km/h, then .
If a body moves in a straight line from a fixed point such that its position vector , where is a unit vector parallel to the straight line, then the average velocity from the beginning of the motion after seconds is .
A car covered a distance of 60 km in one hour, then stopped for half an hour, then moved again a distance of 40 km in the same direction over one hour. Therefore, the average velocity equals km/h.
The driver of car A is moving in a straight line with uniform velocity. He notices car B coming in the opposite direction, and car B seems to be moving with a velocity of 150 km/h. He also notices car C moving in front of him in the same direction, and it seems to be going away with a velocity of 50 km/h. Therefore, the magnitude of the relative velocity of car B to that of car C .
Two cars A and B are moving in opposite directions with velocities of 65 km/h and 75 km/h respectively. If the distance between the two cars is 210 km, then the time taken until the two cars meet is .
- A hours
- B40 minutes
- C90 minutes
- D2 hours
