- Overload
What overload in g (g-force) would have passed the pilot if he accelerated from 0 to 600 km/h in 3 seconds? - Similar triangles
We have similar triangles ABC with angle CAB=45° and angle ACB= 30° and a similar triangle OPN. What is the angle NOP in a similar triangle? - Bicycle wheel turns
The pedal wheel on a bicycle has 28 teeth. The gear wheel on the rear wheel has 8 teeth. How many times does the rear wheel turn if we step on both feet 112 times? How many meters can we travel with it at least, and how much more if the rear wheel has a d - Swing balance
The boy is sitting on a two-arm swing, and his seat is 300 cm away from the center of rotation. Its weight is 48 kg. The girl is sitting at the other end of the swing, and her mass is 36 kg. How far from the center of rotation must the girl sit for them t - Snow White transport
The dwarfs dragged Snow White in a coffin from the garden to the house as Snow White with the coffin was heavy. The dwarves pulled her with a speed of 0.2 m/s. The place where Snow White and the coffin were laid was 15000 cm away from the place in the hou - 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 will it travel if the car starts from Prešov faster? - A discount
A discount clothing store sells a $72 sport jacket for $24 off the regular price. What is the discount rate? - Daily temperature
The average daily temperature measurement for one week every day at the same hour was -2.8 °C. We measured all temperatures on different days are different. The highest daily maximum temperature was 2.4 °C, and the lowest was -6 °C. Determine the options - Begonia seed sowing
The 94 m² flower bed is to be planted with begonias. An area of 2 dm² is needed for one seedling. How many grams of seeds should be sown if 1 g of seeds contains approximately 5000 seeds? Losses when growing seedlings are usually 30%. - Two angles
The triangles ABC and A'B'C 'are similar. In the ABC triangle, the two angles are 25° and 65°. Explain why in the triangle A'B'C 'is the sum of two angles of 90 degrees. - Circles
In the circle with a radius, 7.5 cm is constructed of two parallel chords whose lengths are 9 cm and 12 cm. Calculate the distance of these chords (if there are two possible solutions, write both). - Dress fabric
To sew a dress, you need 2 meters of fabric 150cm wide. How many meters of cloth do we need for the same dress if the fabric is only 90 cm wide? - Highway distance speed
The car is allowed to drive on the highway at a maximum speed of 130 km/h. What distance can he travel in 1.5 hours? Which is the furthest city that a driver can reach in 1 hour if he follows traffic regulations and drives from Prague on the highway to Br - Tunnel
Kubo sits on a train speeding at 108 km/h. At that moment, the train enters the tunnel, which, according to Kub's book, is 2 km long. Kubo notices that the end of the train has left the tunnel 75 seconds later than the locomotive has entered the tunnel. W - Car deceleration
The car is traveling at a speed of 54 km/hour. The driver starts braking with an acceleration (deceleration) of 3 m/s². Specify the time in which to stop. - 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? - Ton kilogram percentage
How many kilograms is 24% of 30 tons? - Four sides of trapezoid
The trapezoid is given by the length of four sides: 40.5, 42.5, 52.8 35.0. Calculate its area. - An acceleration
The car goes on a straight road at a speed of 72 km/h. At some point, the driver starts to brake and stops the car in 5 seconds. Find: (a) the acceleration during braking and (b) the distance traveled during braking. - Car acceleration
The driver of a car traveling at a given moment at a speed of 72 km/h decides to overtake a car traveling at the same speed. Therefore, during 4.0 seconds, increase the speed to 90 km/h. Calculate how big his acceleration was and what path he covered when
