Mrs. Černá left Pardubice and drove to Rychnov nad Kněžnou at an average speed of 60 km/h. At the same time, Dáša set off on her bicycle from Rychnov nad Kněžnou toward Pardubice at an average speed of 25 km/h. The point on the road where they passed each - In the parking lot
At a parking lot 20 km from Bratislava thieves stole car A; it is moving at speed V: 130 km/h towards Žilina. After twelve minutes the motorway police received at the beginning of the motorway in Bratislava an order to catch up with the stolen car and sto - The tourist The tourist came started from the hostel at an average speed of 5 km/h. Half an hour later, the bicyclist started along the same route at a speed of 20 km/h. How many minutes will a cyclist catch up, and how many kilometers will he goes?
- Three Cars on Route
On the 182 km route, car A left at 9:00 a.m., car B at 9:30 a.m., and car C at 9:45 a.m. All three cars reached their destination at the same time. The average speeds of cars A and B differed by 6.5 km/h. How much did the average rates of cars A and C dif - Cycling Speed Comparison Jerry cycled a 100-meter distance at a speed of 30 km/h. What speed would she have to go to get it in a time equal to the world record in the 100 m sprint (WR t = 9.58 s)?
- Overload
What overload in g (g-force) would have passed the pilot if he accelerated from 0 to 600 km/h in 3 seconds? - Water mixing
How many liters of hot water at 80 °C do we have to mix with water at 10 °C to get 10 liters of warm water at 45 °C? - Chair Pressure Floor Area
The weight of the pupil and the chair is 52 kg. The area of the contact surfaces of the chair with the floor is 12 square centimeters. What pressure does the chair put on the floor? - Tank Weight Pressure Ground
The tank's weight is 36 t, and the total contact area of the belts with the ground is 4 square meters. What pressure does the tank cause on a horizontal surface? - Hydraulic press
A force of 60 N acts on the smaller piston of a hydraulic press, 24 mm in diameter. What is the pressure in the liquid below the piston? How much compressive force is produced on the larger piston with a diameter of 420 mm? - Sand
The maximum weight of the car is 5000 kg. We must transfer 10 m³ of sand. How many times does a car have to go? (density of sand is 1500 kg/m3) - Granite cube statue
What is the weight of a granite cube with an edge length of 75 cm if one m³ of granite weighs 2.7 tons? - Cyclist meeting Martha will leave Včelná on a bicycle at 12 km/h. From Holešovice, which is 32 km from the village of Včelná, at the same moment, Eve will drive towards it at a speed of 18 km/h. How long and where will they meet?
- Glass Door Panel Weight
What is the weight of the glass door panel if it is 5 mm thick, 2.1 m high, and 6.5 d wide? The density of glass is 2.5 kg/dm³. - Exponential warm
Suppose that a body with temperature T1 is placed in surroundings with temperature T0 different from that of T1. The body will either cool or warm to temperature T(t) after time t, in minutes, where T(t)=T0 + (T1-T0)e^(-kt). If we placed jello salad at 30 - Trains on Equator
