- Cycling trial
The racer in the cycling time trial rode at a speed of 12 meters per second. How many km has he covered in 3/4 hours? - Average speed
A car drove on one section of the highway for half an hour at 80 km/h. Then the driver reduced the speed to 60 km/h and traveled for three-quarters of an hour. What was the average speed of the car? - Shortcut
The road from the cottage to the shop 6 km away leads either along a straight road that the bicycle can drive at a speed of 18 km/h or by "shortcut". It measures only 3.6 km. But the road from the cottage is all uphill - at a speed of 8 km/h, you can go h - Speed of light
Calculate the speed of light if a distance of 3000 km travels in 0.01 s. - At the beginning 3
At the beginning of motion, a car was going at a speed of 120 km/h and kept this speed for the first 11 seconds. Then it began to accelerate further such that every second it accelerated by 6 km/h until it reached a speed of 150 km/h. Then it began to dec - Gas pressure
The mean square velocity of the gas molecules is 1200 m/s. What pressure does this gas exert on the vessel wall when its density is 0.03 kg/m³? - Cathedral roof sphere
Cathedral height is 110 m, sphere weight 6000 kg, dome diameter 43 m, crane arm length 25 m a) what was the diameter of this sphere? b) how much mechanical work had to be done to lift it to the designated place? - Car speed The car covered the track 157.5 km in 2 hours and 15 minutes. How fast was he moving?
- Deceleration In a braking test, a vehicle that travels at 51 km/h stops in 5 s. What is its acceleration?
- The car The car weight 1280 kg and increased its speed from 7.3 m/s to 63 km/h on a track of 37.2 m. What force did the car engine have to exert?
- Bike meeting
John and William agreed that on Saturday at 7:00 AM, they would go on a trip on their bikes. John fell asleep and started an hour later. When and where will the friends meet? We know that William walked at an average speed of 15 km/h and John at 25 km/h. - Vehicle acceleration
I have specified that the vehicle has an acceleration of 2 m/s², and I need to find out how many meters it will travel if it reaches 64 km/h and also states how long it takes for the vehicle to travel every one meter. - Car cyclist pursuit
At 6.40, a cyclist started from the station at a speed of 12 km/h. At exactly 10:00, the car followed him at a speed of 84 km/h. What time does the car catch the cyclist? - The bomber
An aircraft flying at an altitude of 1260 m. From what distance in front of the target must a parachute load be dropped from an airplane? The load slopes at a speed of 5.6 m/s and moves in the direction of movement at 12 m/s. What is the direct distance o - Pedestrian cyclist meeting From two places, A and B, 27 km apart, a pedestrian will simultaneously walk at a speed of 6 km/h from place A and a cyclist at a rate of 24 km/h from place B. At what distance from place A will they compete?
- Car acceleration time The car starts with constant acceleration, and at a distance of 567 m, it has a speed of 12.6 m/s. How long will it take from the start?
- Body energy
A body weighing 2 kg falls from a height of 45 m in a free fall. What will be its potential energy and total mechanical energy after 2 s from the beginning of the movement? - Car acceleration runway The car reaches a steady acceleration in 24 seconds from a standstill speed of 100 km/h. What runways will he reach on departure?
- Aircraft bearing
Two aircraft will depart from the airport simultaneously. The first flight flies with a course of 30°, and the second with a course of 86°. Both fly at 330 km/h. How far apart will they be in 45 minutes of flight? - Long hot dog
In Kostelec above Black Forest, they made a record-long hot dog. When he slowly moved it to the square, one of the spectators decided to measure its length: the size of his footprint was 28 cm; he measured 20 feet in the travel direction and counted 5 fee
