- Acceleration and force
On a sphere weighing 100 g, which lies on a horizontal plate, a force acts in the horizontal direction, which gives it an acceleration of 20 cm/s². Find the magnitude of the force. - A turtle 2
A turtle can walk 1/12 of a kilometre in an hour. The turtle is 1/5 of a kilometre away from a pond. How long will it take the turtle to reach the pond at this speed? - Trapezoid floor slats
The room has a trapezoidal floor plan; we need to polish it. The parallel sides in a trapezoid are 4,800 mm and 4,400 mm long, and the oblique sides are 4,600 mm and 5,100 mm long. There are two 900 mm wide doors in the room. One strip measures 250 cm and - The ladder
The ladder makes an angle of 2°30' with the wall and reaches a height of 2.3 m. How far is the ladder from the wall? - Cosine
Cosine and sine theorem: Calculate all unknown values (side lengths or angles) from triangle ABC. c = 2.9 cm; β = 28°; γ = 14° α =? °; a =? cm; b =? cm - Renovation
Five doors with a width of 80 cm and a height of 2 m need to be sanded and wallpapered on both sides. One roll of wallpaper with wood decor measuring 80*1000 cm costs CZK 66. How many roles will we need for the renovation? - The chimney
How high is the chimney if we see it from a distance of 60 m at an angle of 42°? - Mallet
Who has the longest mallet if Johnny's is 1,205 m long, George's is 124 cm long, and Frank's 1245 mm long? - Car travel
How many kilometers did the car travel if it averaged 68 km/h? It started at 8:20 and arrived at its destination at 10:05. - Map scale distance The map has a scale of 1:2500000, and we measured a distance of 4 cm on the map. What is the distance in km?
- Step map distance
Peter takes a step of 0.5 m and walks a hundred steps. How long would this distance be on a 1:1000-scale map? - The tailor
The tailor estimated the rest of the fabric in the package at 11 m. By measuring, he found that he could cut the same pieces of this fabric without a residue in 150 cm or 210 cm increments. How many meters of fabric were in the package? - Unit fraction writing
Write the fraction that represents which part: 1) 31 m is of a kilometre 2) 42 seconds is of a minute 3) 10 hours is of a day - 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 - Two places
The actual distance between the two places is 105 km. Find the scale of the map on which this distance is marked by a line 1.2 dm long. - Map trip length
The tourist map has a scale of 1:40 000. Find the actual length of the trip, which is marked on the map by a 7 cm long line. - Triangle land fencing
The land has the shape of an obtuse triangle with sides of 40 m, 30, and 60 m. Determine the minimum mesh length for fencing and the land area in ares. - Cube-shaped box
The cube-shaped box with a length of 20 dm is filled with sand. If 1 m³ of sand weighs 1.5 t, what is the weight of sand? - The train
The train starts for 2 min with an acceleration of 25 cm/s². What speed will he gain in this time, and what path will he pass? - Aircraft acceleration trajectory
The aircraft, which has a speed of 1080 km/h, starts moving for 1 minute with an acceleration of 1 m/s². What will be its final speed? What trajectory will he take at this minute?
