- Hare 2024m
A hare participated in a race 2024 metres long. From the starting line he pushed off with his left foot and throughout the race he regularly alternated left, right, and both feet. When the hare pushed off with his left foot, he jumped 35 dm, when he pushe - Car acceleration distance
How far must a car travel to reach a speed of 72 km per hour if it starts from rest in a uniformly accelerated motion with an acceleration of 0.2 meters per second²? - Stone kinetic energy
What is the kinetic energy of a stone weighing 1 kg that falls in free fall 5 seconds from the start of its motion? g= 10 m/s squared. - Water tube pressure
Water flows in a horizontal tube at a speed of 2.24 m/s and has a pressure of 0.1 MPa. How fast does the water flow in the narrowed part of the tube if its pressure is 0.09 MPa? - Car braking force
What constant braking force is required to stop a car weighing 1 ton in 10 seconds traveling at 50 km/h? - Aquarium water liters
We are to fill an aquarium with a bottom dimension of 30 cm x 30 cm with water. How many liters of water will we need if we pour water to a height of 20 cm? - Crane load path
The crane lifts the load in a uniform, straight line to a height of 8 m and simultaneously moves in a horizontal direction to a distance of 6 m. What path did the load cover? What was the resulting velocity of the load if it took 50 seconds to move it - Seed mixture tons
Farmers on Mr. Dvořák's farm sowed 3.5 tons of feed mixture seeds after the harvested wheat. This seed was blended from oats and vetiver. We know that 1t of this seed was worth 2840 CZK, 1t of oats 3000 CZK, and 1t of vetiver 2800 CZK. From how many tons - Tram - safe downhill
What is the maximum angle at which the tram can go downhill to still be able to stop? The coefficient of shear friction is f =0.15. - Alcohol concentration mixing
In the hospital laboratory, two containers contained different concentrations of alcohol. After mixing 10 liters of alcohol from the first container with 14 liters from the second container, 75% of the alcohol was formed. If 40 liters from the first conta - Fruit packages
In a sorting room, fruit packages were prepared from oranges and mandarins. Into 35 packages they put the same number of oranges and mandarins. Into another 25 packages they put only oranges. The number of pieces of fruit was the same in all described pac - Two 2 Two different harvesters together harvested potatoes from an area of 6.6 ha in one shift. The area that the less powerful harvester could harvest in six shifts, the more powerful one could harvest in five shifts. Determine the area that each harvester cou
- Granite buoyancy pressure
A granite cube with an edge length of 1 dm and a weight of 2.5 kg is completely immersed in a container of water. How much buoyancy does it lighten? How much pressure does the cube exert on the bottom of the container? - Nozzle water speed
A water spray nozzle with a cross-section of 1.5 cm² sprays water at a speed of 24 m/s. What is the speed of the current in the supply pipe whose cross-section has a volume of 18 cm²? - Roofer roof days
Three roofers cover a third of the roof in 10 days. In how many days would 5 roofers cover the entire roof at the same rate? - Tree watering distance
There are 10 trees in a row with the same spacing x = =3 meters. How many meters does a person travel if he waters two trees at once - Body current voltage
A current of 0.1 A can lethally affect a human body with a resistance of 3 kΩ. What voltage corresponds to this current? - Bulb voltage current
A current of 275 mA passes through the filament of a light bulb with a resistance of 800 Ω. What voltage is the bulb connected to? - Lever force distance
Calculate at what distance from the axis of rotation a force of 60 N acts on one side of a double-return lever; if a force of 180 N acts on the other side at a distance of 1 meter from the axis of rotation, the lever is in equilibrium. - Karel digit error
Carl had to multiply two two-digit numbers. Out of care, he changed the order of the digits in one of the factors and got a product that was 4,248 less than the correct result. What is the correct result? How much should Karl have earned?
