- Brakes of a car
For the brakes of a passenger car to be effective, it is prescribed that a car be moving on a horizontal road at a speed of 40 km. A car must stop on the track 15.4 m. What is the deceleration of the car? - Motion against
From two places 36 km apart, a pedestrian and a cyclist will go straight opposite each other. How long will they meet if the speed of the pedestrian is 4 km/h and the cyclist 12 km/h? - Travel Time for Distance
Students want to get from Žilina to Bratislava for a concert by a well-known music group. The distance between these places is 200 km. The estimated average speed is 80 km per hour. How long will it take them to travel? - Train distance
Two trains traveling in opposite directions meet at 8:00. How many km apart are they at 8:20 when one goes at 75 km/h and the other at 120 km/h? - The tram
The tram is moving with acceleration a = 0.3 m/s2. How long will it pass the first meter of the track? How long does it take 10 meters? What is its speed at the end of the 10-meter track? - Rifle recoil
A projectile weighing m1 = 0.01 kg is fired at a velocity v1 = 800 m/s from a rifle weighing m² = 4 kilograms. - Car distance
The car was traveling at a speed of 112.5 km/h. Determine what distance he would have walked in 144 minutes if he had kept going at the same pace. - Scale of map
James travels one kilometer in 12 minutes. The route was walked for half an hour, measured on the map 5 cm. Calculate how many kilometers James walked for half an hour. Find the scale of the map. - 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? - Journey to grandma
Daniel traveled to Grandma. He traveled 100 km, halfway by train, one quarter by bus, one-tenth by bicycle, and the rest by car. How many km did he travel by car? - Cars
Cars started at 7:00 AM. From point A, the car runs at 40 km per hour, and from B, the car runs at 70 km per hour. Between A and B is a 250 km long road. When and where will they meet (measured from point A)? - Two cars
Car A1 goes at an average speed of 127 km/h, and the second car, A2, goes at 122 km/h. How many seconds will it take car A1 to circulate car A2? Assume that both cars are 4.7 meters long and the safety gap between cars is 2.6 meters. - Calculate 449
Calculate the size of the angle formed on a clock face by the lines connecting the centre to the positions at 7:12 and 1:24. - Acceleration - gravity
What is the gravitational acceleration if a body with a mass of 5.8 kg fell from 68 metres and hit the ground at a speed of 60 km/h? - Resistor resistance calculation
At a certain point, we measured a voltage of 3.74 V at a current of 170 mA at the terminals of a resistor connected to an electrical circuit. Calculate the resistance of the resistor. - Tiles
The pupils of the building school have to calculate how many roof tiles they will need to cover the roof of the house in the shape of two rectangles measuring 10 x 7.2 m. One roof tile covers a rectangular area of 22 cm x 32 cm. How many tiles will they n - Hall
A rectangular hall is to be paved with square tiles with a side length of 15 cm. The hall has a length of 18 meters and a width of 3 m. How many tiles do you need to buy if 2 percent of the amount are damaged during the work? - Rectangular land
Due to the new road, the longer dimension of the rectangular plot had to be shortened by 4 percent, and the shorter dimension shrunk by 10 percent. Thus, the area of the land has decreased by how much percent? - Cadastral map scale
Calculate the scale of the cadastral map, on which the square plot has a circumference of 20 cm and, in fact, 576 m. - Three gardens
Is it possible to divide a plot of land with an area of 927 m² into three gardens in a ratio of 4:2:3 so that their areas are only whole multiples of square meters?
