We threw the stone vertically upwards at a speed of v = 15 m/s. How long will it be at a) 10 m, b) 12 m? - Swimming pool
Thaddeus set off on foot to the swimming pool, which is 18 km from his residence. The trip took him two and a half hours. An hour later, his brother William met him on his bicycle, whose journey took three-quarters of an hour. a) Show the described situat - Bratislava BA-BB
A truck drove from Bratislava to Banská Bystrica at a speed of 30 km/h. At the same time, a tractor drove at a speed of 40 km/h. The tractor arrived in Banská Bystrica 1 hour and 45 minutes earlier than the truck. What is the distance between the cities? - Cyclist stage speed In the first stage, the cyclist covered 70 km at a speed of 22.1 km/h. In the second stage, he covered 40 km (a total of 110 km), and his overall average speed increased to 22.9 km/h. What average speed did he achieve in the second stage?
- Highway section length
A passenger car drove a highway section at a constant speed. At a speed of 20 km/h higher, the ride would take 6 minutes less. At a speed of 20 km/h lower, it would take 9 minutes more. Calculate the length of the highway section. - Machine product hours
The machine will produce 5,600 products in 7 hours. How many products will they make in 8 hours? - Mountain and hiker
The hiker set out on a hike at 5 km/h. After 30 minutes, a cyclist on a mountain bike set off on the same route at 20 km/h. After how many minutes will the cyclist overtake the hiker? - Tachometer speed error
The tachometer with a relative measurement error of 5% showed a speed of 49 km/h when crossing municipalities. Did the car driver exceed the permitted speed of 50 km/h? - Cyclist car journey The cyclist travels 10 km per hour, car 60 km. The cyclist went for 3 hours. How many minutes does the same journey take to a car?
- Car kinetic energy
A railway car weighing 10 t moves around the Earth at a speed of 10 m/s. Determine the kinetic energy of the car relative to the Earth and relative to another car moving at a speed of 10 m/s relative to the Earth, both in the same direction and the opposi - Car meeting time At 10:00 AM, a car started from place A at a speed of 70 km/h. 0.5 hours later, a car started from the same point at a speed of 100 km/h. What time did they meet? How many kilometers from point A did they travel before they met?
- Body collision momentum
A body with a mass of 4 kg hits an obstacle at a speed of 10 m/s. After the collision, the body continued to move at a speed of 6 m/s, while the direction of this speed was perpendicular to the direction of the speed before the collision. Find: a) change - Driver speed limit
The driver must not exceed the maximum allowed speed of 90 km/h. Can he make the 145 km journey from Cheb to Teplice in an hour and a half? - Twelve-minute run
Runner Adam performs a twelve-minute training run every day. He starts running at a speed of 3.5 m/s and every three minutes he increases his speed by 0.5 m/s. At the end of the first section, the cyclist Eva overtakes the runner, who is riding at a const - Acceleration and force
On a sphere weighing 100 g, which lies on a horizontal plate, a force acts in the horizontal direction, which gives it an acceleration of 20 cm/s². Find the magnitude of the force. - The cyclist - avg speed
The cyclist make a distance of 25 km at an average speed of 20 km/h. How long did the trip take him (in hours and minutes)? - A turtle 2
A turtle can walk 1/12 of a kilometre in an hour. The turtle is 1/5 of a kilometre away from a pond. How long will it take the turtle to reach the pond at this speed? - Radio radius
Two friends have shortwave radios with a range of 13 km. The first of them travels by train at a speed of 48 km per hour along a straight section of track, from which the second of the friends is 5 km away. How long will radio friends be allowed for both - Raindrops
The car runs on a horizontal track at a constant speed of 20 m2-1. It is raining. Raindrops fall in a vertical direction at a speed of 6 m/s. a) How fast is the speed of the drops relative to the car windows? b) What is the angle of the raindro
