A poll carried out among 200 students of one school found out which of the singers V. Neckář, K. Gott, W. Matuška is the most popular. It brought the following results: Gott is popular with 78 students, Matuška with 75 students, and Neckář with 101. It wa - 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? - 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. - Red candles
For Christmas, the Veselá family made gel candles. Father Veselý filled an entire jar with green gel. Mother Veselá filled one sixth of the jar with green gel and the rest with red. The daughter used the same amount of green and red gel. The son poured on - 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

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. - 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?
- Adam Fero money
Adam had 3 times more than Frank. Gabo is 11 less than Frank. They had a total of 59 euros. How much did each have? - Train 2
A metro train moved between neighbouring stations as follows: it gradually accelerated and reached a speed of 70 km/h in 10 seconds. It then travelled at this speed for 35 seconds. Finally, it decelerated for 15 seconds until it stopped. Draw the speed-ti - Car braking acceleration The car stopped at an initial speed of 90 km/h on a track of 62.5 m. What was its acceleration, and how long did it take to brake the car?
