- Car tractor pursuit
Behind the tractor, which travels at 12 km/h, they sent a car 3.5 hours later to catch up with him in 45 minutes. What speed does he have to go? Please also explain the procedure. - Achilles and the turtle
It is known that Achilles will not catch up with the turtle. But his brother Auchalles can do it. He even gave the turtle an 8-hour lead. Calculate how far from the start Auchalles will meet a turtle moving at an average speed of 70 m/h if Auchalles walks - RPM
An electric motor makes 3,000 revolutions per minute. How many degrees does it rotate in one second? - Two parts journey
The driver of the car plans to drive 30 km in 0.5 hours. For 20 minutes he follows the convoy (traffic jam) at a speed of 30 km/h. What speed would he have to go in the remaining time? - Car speed compliance
Police found that the car had traveled 300 m in 20 seconds. He complied with the driver's maximum allowed speed of 50 km/h - Accelerated motion - mechanics
With a total weight of 3.6 t, the delivery truck accelerates from 76 km/h to 130 km/h in the 0.286 km long way. How much was the force needed to achieve this acceleration? - Braking distance
The car travels at an average speed of 12 km/h and detects an obstacle 10 m in front of it. At 1 m in front of the obstacle, it already runs 2 km/h. What is the braking distance? What is the required deceleration for a stop: A) 1 m B) 1 s? - Trip kilometers
The route of the tourist trip measures 28 cm on a map with a scale of 1:50000. The average walking speed is 4 km/h. How many kilometers does the trip measure? How many hours will the students spend on the trip? - Cyclist Speed Meters Seconds
If a cyclist rides at a speed of 54km/h, how many meters will it cover in 5 seconds? - Avg speed of flight
The student's vice adventure had a 2,367 km flight. If their travel time was 2 hours and 56 minutes, what was their average speed in kilometers per hour? - Friction coefficient
What is the weight of a car when it moves on a horizontal road at a speed of v = 50 km/h at engine power P = 7 kW? The friction coefficient is 0.07 - Raindrops
The train is moving at a speed of 60 km/h. Raindrops falling vertically in the absence of wind (with uniform movement due to the action of air resistance) leave traces on the windows of the train, deviating from the vertical direction by 30°. How fast are - Walking
The boy walked about 8.5 km in an hour. How long will it take to walk a distance of 32 km if he takes two breaks of 30 minutes during the route? - Driver Speed Increase Time
The driver covered the distance between the two cities in 2 hours at an average 75 km/h speed. How did he change speed to get 20 minutes faster? - Cyclist pursuit
The pedestrian walks at a speed of 4.3 km/h. In 1 hour and 10 minutes, a cyclist followed him at an average 18 km/h speed. How many minutes will a cyclist reach a pedestrian, and how many kilometers will he travel? - Velocipedes
In the 19th century, bicycles had no chain drive, and the wheel axis connected the pedals directly. This wheel diameter gradually increased until the so-called high bikes (velocipedes) had a front-wheel diameter of up to 1.5 meters, while the rear wheel w - Car and motorcyclist A car and a motorcyclist rode against each other from a distance of 190 km. The car drove 10 km/h higher than the motorcyclist and started half an hour later. It met a motorcyclist in an hour and thirty minutes. Determine their speeds.
- Under the sea
In Jules Verne's famous novel "Twenty Thousand Leagues Under the Sea", three heroes – professor Aronnax with his servant Conseil and the harpooner Ned Land – experience a journey by submarine Nautilus under the command of captain Nemo. Suppose that the av - Grandmother Mom walked out to visit her grandmother in a neighboring village 5 km away and moved at a speed of 4 km/h. An hour later, father drove down the same road at an average speed of 64 km/h. 1) How long will it take to catch Mom? 2) What is the approximate dis
- Ant ruler running
A frightened ant runs along a 16 cm long ruler at a constant speed of 1 cm per second. He always turns around and runs back after reaching the end of the ruler. Each turn takes 1 second. He started running from the left corner. Next, how many numbers will
