- Filip Monika meeting
Philip traveled 15 km from Monica's house to his grandmother's village. Monika can visit him. They meet at the point where the bikes arrive. They both left the house at 9:00. At what time did they meet when Philip was walking at a speed of 19 km/h and Mon - Accelerated motion
The position of a mass point that moves along the x-axis is given by the relation x=10t²-5t. Express its velocity and acceleration. - Ground speed
The plane flies south at an average speed of 190 km/h, and the wind blows from west to east at a speed of 20 m/s. How fast and in what direction (relative to the meridian) will the plane move relative to the ground? - Swimmer pool meeting
The pool is 50 m long. The first swimmer swims across it in the 60 s and the second in the 40 s. Both start at the same time and on the same side. The faster swimmer turns around at the end and swims back. When will he meet the slower swimmer? Swimmers mo - Train speed direction
Soňa is sitting on the train, looking out the window, and what she doesn't see is that the landscape runs backward at a constant speed of 160 km/h, and on the side track, the train is seemingly backing up at a constant speed of 40 km/h. Sonia stops and wo - Object final velocity
The object has a speed of 25 m/s and accelerates 5.0 m/s² for 250 meters. What is the final velocity? - Car acceleration speed
The car has a speed of 5 m/s and accelerates to 35 m/s in 12 seconds. Calculate the acceleration of the car at a speed of 34.5 m/s. - Gear wheel rotation
Two gears mesh together. The larger wheel has 56 teeth, and the smaller wheel has 20 teeth. How many times does the smaller wheel turn if the larger wheel turns 15 times? - Passenger train At 9:15 AM, a passenger train passes a station at a speed of 75 km/h. At 10:00 AM, an express train passes through the same station in the same direction at a speed of 120 km/h. Both trains arrive at the same destination station at the same time. a) At wh
- Plane sound echo A plane flying at 612 km/h speed sent a sound signal. In front of the aircraft (in the direction of flight), there is a fixed object at a distance of 3 km, from which the sound is reflected back to the plane. How long will it take the pilot to hear the ec
- Body trajectory energy A body of mass 4 g is shot perpendicularly from the ground and lands in 8 s. What is its kinetic energy at the beginning of its trajectory, what speed does it take off, and where does the distance from the ground stop?
- Karel Ondra pursuit Carl went for a walk at a speed of 5 km/h. After 3 hours, Andrew rode after him with an important message at a speed of 20 km/h. How many minutes did it take Andrew to catch up with Carl?
- Ball collision speed
Two inelastic/plastic balls move towards each other with equal velocities of 2 m/s. The weight of one ball is 3 kg, the other 1 kg. Determine the speed of the balls after the collision and the loss of kinetic energy. - Flywheel energy decrease
How much energy was supplied by the flywheel of the device if its number of revolutions decreased from 1200 to 720 revolutions per minute if it has a moment of inertia of 71.3 kg/m²? - Makarska riviera
The motor boat departs from Baška Voda at 19:15 and arrives in Makarska at an average speed of 30 km/h at 20:00. However, a group of tourists from Germany must be in Makarska a third of the time earlier. What should the average speed of the boat be? - Vehicle speed ratio The speeds of two motor vehicles are in the ratio 7:4. How many kilometers will the slower vehicle travel simultaneously, if the faster vehicle travels 52.5 km?
- Runner training duration
How long will training for an endurance runner last if he plans to run 36 km at a speed of 5 m/s and spends 35 minutes warming up? - Lukas Jakub pursuit Luke left the Tereza cottage and walked at an average 4 km/h speed. Forty-five minutes later, Jacob followed him on a bicycle from the same cottage. He followed Luke's route and caught up with him after 20 minutes. What was Jacob's average speed?
- Boaters - boat
In summer Marek and Lukáš go on trips in a motor boat. On calm water the boat moves at a speed of v0 = 16 km/h. Both boys set out on a voyage along a river, the water in it relative to the bank moves at a speed of v1 = 4.0 km/h. They set off from the boat - Express train distance The express train leaves place A at 19:20 and arrives in town B at 20:24. The average speed of the express train is 15 m/s. What is the distance between cities A and B?
