- Artificial 57081
Determine the average speed and orbit of the Earth's first artificial satellite. Its distance from the Earth's surface in the perigee was 226 km, and in the apogee, 947 km. - 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? - Acceleration 56621
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? - Change per hour
On Sunday, the temperature was 63 degrees at 2 PM. The temperature was then 72 degrees at 5 PM. What is the rate of change per hour? - The cyclist
The cyclist reaches a speed of 32 km/h in 3.4 seconds. What is its acceleration in m/s²?
- The projectile
The projectile leaves the 10 m long barrel at an instantaneous speed of 500 m/s. What is the acceleration of the movement of the projectile in the barrel, and at what time will the projectile pass the barrel if we assume that It evenly accelerated the mot - The car
The car has a consumption of 5 liters per 100 km. It has 24 liters of gasoline in the tank. How much petrol remained in the tank when it rides for two and a half hours at a speed of 80 km/h? - Day trip
A group of tourists went on a day trip. For two hours they walked at a speed of 6 km/h, for another hour they climbed a steep hill at a speed of 2 km/h, spent an hour and a half at lunch, then in an hour they inspected the castle garden at a free step at - The temperature 13
The temperature in Toronto at noon during a winter day measured 4°C. The temperature started dropping 2° every hour. Which inequality can be used to find the number of hours, x, after which the temperature will measure below -3°C? - Two cars
Two cars (trucks and passengers) drove simultaneously from two places 50 km away. If they go against each other, they will meet in 30 minutes. If they follow each other in the same direction, the car will catch up with the truck in 2.5 hours. What is the
