- Fog
The car started in fog at a speed of 30 km/h. After a 12-minute drive, the fog dissipated, and the driver drove the next 12 minutes distance, 17 km. The driving conditions deteriorated during the last 17 km long, and the driver drove at 51 km/h. a) Calcul - Car - road
The car started at 11:40 at a speed of 54 km/h from A, and to B arrived at 12:20. Find the distance between A and B. - Two trains
Two trains go at each other. First at a speed of 40 km/h and the second at a speed of 60 km/h. At what distance will it be 30 minutes before they will meet? - Distance between two cities
The car went from A to B in 4 hours. The car was up 15 km/h faster on the way back. The return trip took 48 minutes shorter than the way there. Find the distance of cities A and B.
- Inclined plane
On the inclined plane with an inclination angle of 30°, we will put the body (fixed point) with mass 9 kg. Determine the acceleration of the body motion on an inclined plane. - Train 2
The train slowed down from 90 km/h to 72 km/h in 5 seconds. How long does track travel? - Acceleration
The car accelerates at a rate of 0.5 m/s². How long does it travel 400 meters, and what will be its speed? - Motion 2
At 10 o'clock started, place A car's speed at 90 km/h. Twenty minutes after starting another car from place B at a speed of 60 km/h. The distance between places A and B is 120 kilometers. What time and where do they meet? - Vacation
Parents are piggybacking children on vacation to their grandmother and grandfather in a city distant 150 kilometers. They agreed to meet halfway. Parents will travel at 90 km/h, grandmother and grandfather at 60 km/h. Parents depart at 12:00 hours. When d
- Cars motion
From A point car starts at the speed of 90 km/h. Against it departs from point B at the same time another car at 60 km/h. How long and where do they meet if the distance between A and B is 180 km? - Passenger 1810
The distance between cities A and B is 165 km. A truck traveled from city A to city B at a speed of 50 km/h. Fifteen minutes later, a passenger drove from city B to city A at 72 km/h. How far will the passenger car travel before the two cars meet? - Tourists
The first group of tourists started from the cottage at 7:00 AM at a speed of 4 km/h. The second started after them 21 minutes later at a 6 km/h. How long and how many kilometers from the cottage will catch the first group? - Znojmo
From Znojmo to Brno started the truck with a trailer at an average speed of 53 km per hour. Against him, 14 minutes later from Brno started the car with an average speed of 1.2-times greater than the truck. How long and how far from Znojmo do they meet if - Cars 2
Opava is 360 km distance from Prešov. At 9:00 hour, two cars started against each other from these cities at average speeds 69 km/h and 79 km/h. What hour will it meet, and what distance it's travel if the car starts from Prešov faster?
- Cars
Cars started at 7:00 AM. From point A, the car runs at 40 km per hour, and from B car runs 70 km per hour. Between A and B is a 250 km long road. When and where will they meet (measured from point A)? - Racer
The first racer runs at a speed 20 m/s and is 750 meters before the finish and ahead 79 meters before the second competitor. At what speed must run the second racer catch the first racer at the finish line? - Car
The driver of a car is to get to 608 km distant city. The atlas found that 162 km will have to pass through the cities at an average speed of 48 km/h. The remainder of the journey passes outside the cities at an average speed of 116 km/h. Calculate how ma - Two runners
Two runners ran simultaneously towards each other from locations distant 34.6 km. The average speed of the first runner was 1/5 higher than the average speed of the second runner. How long should each run a 34.6 km, if you know they meet after 67 minutes? - Circular motion
The mass point regularly moves in a circle with radius r = $r m angular velocity ω = 4.3 rad/s. Calculate the period, frequency, and centripetal acceleration of this movement.
