- Car meeting location
Cars left two places 520 km apart simultaneously at speeds of 30 km/h and 50 km/h. Where and when will they meet? - Beetle cabbage pursuit
Theodore the beetle set off from the house towards the cabbage leaf at a 20 m/min speed. Two minutes later, Max the beetle followed him at 24 m/min speed. They both came to the cabbage leaf at the same time. How far was the cabbage leaf from their house? - Car distance remaining The car travels from Prague to Brno at a speed of 80 km/h and still has 15 minutes to drive. How far is it from Brno?
- Doppler effect
The observer moves away from the source at a speed of 12 m/s. The source produces sound with a frequency of f=475 Hz. What is f2 (frequency of sound perceived by the observer)? v= 340 m/s. - Airplane distance meeting
Two points are at a distance of 1840 km. An airplane departs from A at 7:00 a.m. and flies at an average speed of 50 km/h faster than another airplane departs from B at 8:00 a.m. At what distance from A do they meet at 9:00? - Disc angular speed
1. A disc makes 15 revolutions per minute. Determine his angular speed and the boy's speed on the seat that describes a circle with a radius of 5 m. 2. The grinding wheel rotates at 600 revolutions per minute. Determine the period and angular velocity. Th - Coefficient of friction A car moves along a horizontal road at a speed of 15 m/s. After turning off the engine, the car traveled a distance of 225 m. What was the coefficient of friction for this motion?
- Bus highway speed Tourists traveled by bus to Croatia. They drove the highway in 8 hours at an average speed of 100 km/h. How fast would they cover it if they walked at an average speed of 120 km/h?
- Free fall velocities
Calculate the instantaneous free fall velocities at the end of the 1st, 3rd, 5th, and 7th seconds. Compile the results in a table. - Cyclist peloton speed
The front of the cycling peloton travels at an average speed of 48 km/h. The cyclist with the green T-shirt lost 5 minutes when he fell. What speed must he drive if he wants to reach the front of the peloton in twenty minutes? Possible? - Siblings 6
Siblings Martin and Judy decided to visit a castle 10 km from their home. Martin left at 7:30 and walked at a speed of 4 km/h. Judy set off on her bicycle an hour and a half later and rode at 16 km/h. Did Judy catch up with Martin before the castle? If so - Motorcyclist gully fall An undisciplined motorcyclist drove at an unreasonable speed on a mountain road, lost control in a bend, and left the roadway at 90 km/h. He was falling into a gully 36 m deep. Draw a cross-sectional picture of the whole situation. How far did the motorcy
- Tank inlet filling
The fire tank is filled with three inlets, each flowing 6 liters per second in 12 hours. How long will it take to fill if 8 liters per second flow through each of them? - Kerosene pressure difference
Kerosene (ρ1 = 830 kg . m-3) flows through the pipe. Calculate the pressure difference in the given sections when the mercury level difference (ρ2 = 13600 kg . m-3) in the mercury differential manometer is h = 2.2 dm. - Water pressure depth Calculate the depth of water at which the hydrostatic pressure is equal to 100870 N/m². We only consider hydrostatic pressure.
- Horse carriage
Hlušice and Jarošov are 10 km apart. A horse-drawn carriage leaves Hlušice for Jarošov at a speed of 5 km/h, and at the same time a traveller leaves Jarošov for Hlušice at a speed of 3 km/h. At the moment the carriage departs, a fly starts from the horse' - Liquid mass volume The liquid has a specific gravity of γ = 9050 N. m-3. Calculate its specific gravity, the mass of 2 m³ of this liquid, and also of 3 m³ of this liquid.
- Liquid specific gravity The hydrostatic pressure at a depth of 6.5 m in an open liquid container is 79.5 kPa. What is the specific gravity of this liquid?
- Hand velocity ratio
The minute hand is three times longer than the second hand. In what ratio are the magnitudes of the velocities of their endpoints? - From city 2
A passenger train left city A for city B in the morning. At the same time, a freight train left city B for city A along the same track. Both trains travelled the entire route at constant speeds. They passed each other on the track at 9:45 a.m. The passeng
