- Projectile height
A 100 g body is ejected vertically upwards from the surface of the Earth at an initial speed of 30 m/s. Determine the height at which the body rises and its potential energy at the path's highest point. - Sikorsky helicopter
The American concern United Technologies is testing the Sikorsky X2 helicopter, which can fly at a record speed of 464 km/h. How long would it take an F22 Raptor fighter flying at a supersonic speed of 1,856 km/h to catch up with a Sikorsky X2 helicopter - Timber log
The ship goes from point x to y. Downstream it takes 4 hours, and upstream 6 hours. How long does it take from a point x to y a log? - Jet distance
What distance (in km) will the jet fly at 500 km/h in 12 minutes? - Travel time
At what time the body travels a distance of 105 km with a steady movement at a speed of 70 km/h? - Cyclist speed
A cyclist covered a track of 40 m in 5 s. The first section of the 30 m track was covered in 3 s; the remaining section was covered in 2 s. Specify: a) the average speed of the cyclist on the first section of the track b) the average speed of the cyclist - Speedboat and train
At 12:15, a train speeding 55 km/h left the station. Twelve minutes later, an 80 km/h speedboat set off behind the train. What time does the express train catch up? How far from the station? - Big celebration
An inseparable part of all big celebrations is the entertainment, during which the participants try to pull off the tablecloth from the set table so that nothing falls from the table on the ground. Let us look at this trick up close. We will start from Ne - Cenda and Pepa
Cenda and Pepa went to the event. Cenda started alone. Canda started after him for 20 minutes. How long did it take Cenda to catch him? Cenda traveling at 15 km/h, and Pepa traveling at 25 km/h. - Cyclist and car A cyclist who runs at a speed of 20 km per hour will arrive at the finish in 4.5 hours. How fast does the car have to drive the same route in 2 hours?
- Fog
The car started in fog at a speed of 30 km/h. After a 12-minute drive, the fog dissipated, and the driver drove the next 12-minute distance, 17 km. The driving conditions deteriorated during the last 17 km, and the driver drove at 51 km/h. a) Calculate th - Car
The car drove some distance in 3 hours and 20 minutes. If it increases speed by 10 km/h, it goes this distance in 2.5 hours. Calculate the distance. - Train expres
At 8.00, the express Tatry started from Bratislava to Poprad. Cities are distant, 340 kilometers. At the same time, it started from Poprad Express Danube to Bratislava. Express Tatry's average speed is 80 km/h, Danube 90 km/h. At what distance from Poprad - Ambulance speed At what speed must an ambulance travel to a traffic accident if medical assistance is provided within 20 minutes? The accident is 22 km from the ambulance station, and the witness was on the phone 5 minutes after the accident.
- Ascent and descent
The car goes 114 km of track, consisting of ascent and descent at 1 hour 35 minutes. When climbing, it moves at the speed of 48 km/h and downhill at 25 m/s. What is the length of the climb and descent? - Sound travel
Sound travels in the air at a speed of about 330 m/s. Make a table of the dependence between the time (after one second), and the sound's distance travels during this time. During a storm, you can easily find out how far you are from it. - Water level
To cuboid-shaped poll, bottom size 2 m and 3.5 m, flows water at a rate of 50 liters per minute. How long will it take for water to reach a level of 50 cm? - Atmospheric pressure
The measured value of atmospheric pressure is 96,000 Pa. We want to verify this value with a closed tube at one end. Before measuring, fill the tube with glycerol (density of glycerol ρ = 1200 kg/m3). How long does the tube have to be? - Train distance
The passenger train is 60 km from the destination station and runs at a steady speed of 54 km/h. How far will it be from the destination station in 45 minutes? - Speed comparison
Arrange the listed speeds from smallest to largest: Š - The sprinter will run 60 meters in 7 seconds, L - chairlift passes 180 meters in 2 minutes, A - the car travels 35 km in half an hour, H - hippo, during the attack, runs 50 meters in 60 seconds.
