- Mr. Gazdíček
Mr. Gazdíček has in the garden two identical tanks for rainwater, which he uses for continuous irrigation. At the last check, there were 1 000 litres in the first tank and 1 200 litres of water in the second. From the first tank water flows at a rate of 1 - Average Speed Walk Hill
The tourist walked on the plain for 2 hours at a speed of 6 km/h. For another hour, he climbed a steep hill at a speed of 3 km/h. What was his average speed? - Disk angular velocity
The speed of the points lying on the circumference of the rotating disk is 6 m/s. The speed of the points, which lie 20 cm closer to the axis of rotation, is 4 m/s. Find the angular velocity of the wheel. - Motorcyclist
From Trutnov, the motorcyclist started at an average speed of 60 km/hour. At 12.30hrs, Peter began driving the passenger car at 80 km/hour. How many hours and at what distance will a car catch a motorcycle from Trutnov? - Pump Fill Tank Time
The pump delivers 0.75 hl of water per minute. How long does it take to fill the tank with a volume of 10m³? Write the result in hours and minutes. - Two ships
The distance from A to B is 300 km. At 7:00 AM, a ferry departed from A toward B at a speed 20 km/h greater than a ship that departed from B toward A at 8:00 AM. They met at 10:24. Find the distance of the meeting point from A and determine when each vess - Uniform Acceleration Initial Speed
The body went through a uniformly accelerated path of 30 m in 10 seconds while its speed increased five times. Find the initial speed and acceleration. - Runner acceleration speed
The runner ran the track 100 m in 10.2 seconds. He ran the first 20 m with a uniformly accelerated movement. Then he ran evenly. What was its acceleration on the 20 m section, and what was its maximum speed? - Acceleration of a train
The train passes 700 m, braking with an acceleration of -0.15 m/s². How long does it break, and what is the final speed of the train if the initial was 55 km/h? - Car braking calculation
The car starts to brake with an acceleration of -6.5 m/s² and stops on the track at 45 m. What were the initial speed and braking time? - Driver
The car driver drove at 100 km/h saw the obstacle and began braking with a slowing of 5 m/s². What is the pathway's length to stop the car when the driver has registered the obstacle with a delay of 0.7 seconds? - Brakes of a car For the brakes of a passenger car to be effective, it is prescribed that a car be moving on a horizontal road at a speed of 40 km. A car must stop on the track 15.4 m. What is the deceleration of the car?
- Car overtaking
A passenger car travels at a speed of 30 m/s; before it travels, a freight truck drives at a constant speed of 10 m/s. Within 30 meters of the truck, the driver of the car finds out that the truck can not overtake. That's why it starts braking with an acc - Two mass points Two mass points start moving simultaneously in the same direction from the same location: the first point moves uniformly at a speed of 50 cm/s, and the second point moves with uniform acceleration from rest at an acceleration of 10 cm/s². Determine: a) t
- Two bodies 2
Two bodies start moving simultaneously from the same place in the same direction. The first body moves with uniform acceleration with an initial velocity of 4 m/s and an acceleration of 0.5 m/s², while the second body moves with uniform deceleration with - Brakes
The braking efficiency of a passenger car is required to stop at 12.5 m at an initial speed of 40 km/h. What is the acceleration braking by brakes? - Two cars 6
Two cars leave the same place one after the other, 15 seconds apart. Both move with uniform acceleration from rest: the first car with an acceleration of 0.5 m/s², and the second car with an acceleration of 2 m/s². Determine: a) the time and distance at w - Ball acceleration distance
A ball placed on an inclined plane begins to move and reaches a speed of 1 m/s in 5 s. Assuming that the ball's motion is uniformly accelerated, determine the magnitude of its acceleration and the distance it travels in the given time. - An acceleration The car goes on a straight road at a speed of 72 km/h. At some point, the driver starts to brake and stops the car in 5 seconds. Find: (a) the acceleration during braking and (b) the distance traveled during braking.
- Tractor braking calculation
A tractor travels along a straight road at a speed of 15 m/s. The tractor driver starts braking with an acceleration of 2 m/s². Specify a) the magnitude of the speed and the path of the tractor in 5 s from the moment it started to brake b) the time for wh
