- 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 - Lady gentleman meeting
The lady and the gentleman run toward each other in an even, straight-line motion. The lady runs at a speed of 25.2 km/h, and the man at a speed of 18 km/h. When they are 300 m apart, we start timing. How long before the lady and the man fall into each ot - Radiators
Calculate the radiator output if it has a thermal gradient (difference between inlet water and return temperatures) a) 5 °C b) 10 °C c) 15 °C d) 20 °C A heating water volume flow is 45 kg/h. How fast the water flows from the supply pipe to the radiator e) - Free fall The elevator car weighing 720 kg, is torn off at the height of 125 m and begins to fall in a free fall. How much kinetic energy did the elevator car have when it hit the ground floor of the building when the free fall of the car lasted 5 s?
- Engine performance
The car's engine develops a power of 1800 N. Find its performance if it travels evenly on a horizontal path at 48 km/h. - G Force, mass A car with a weight of 20 kN travels at a speed of 54 km/h. What is its kinetic energy?
- Free fall 5 Jeremy accidentally dropped his toy stuffed animal from the balcony of his apartment on the fourth floor. The toy hit the ground at a velocity of 16.0 meters per second. At impact, it took 2.0 seconds for the toy's velocity to reach 0 meters per second. I
- Pedestrian cyclist meeting
Cities A and B are 36 km apart. A pedestrian leaves town A at a speed of 6 km/h to place B. A cyclist leaves town B simultaneously at a speed of 24 km/h to town A. In how many hours and at what distance will they meet? Write the result in minutes. - Cindy run
Suppose it takes 1/3 of an hour for Cindy to run 3/5 of a mile. How many miles does she run in 1 hour? - Tourist group meeting From Tatranská Lomnica to Ždiar, 40 km apart, two groups of tourists went opposite each other. Pedestrians left Tatranská Lomnica at 9:00 AM at an average speed of 4 km/h. Cyclists from Ždiar at 9:30 at an average speed of 15 km/h. When will they meet? At
- Earth travel distance
The Earth is moving at a speed of 29.8 km/s, and what track will the Earth travel in an hour? - Brno-Tachov highway The distance Brno-Tachov is 360 km. At 8:00 AM, a car travels from Brno on the highway at an average 90 km/h speed. An hour later, a vehicle leaves Tachov towards Brno, whose average speed is 110 km/h. Calculate how far apart they will be at 11:00 AM when
- Cheetah antelope pursuit The antelope was 100 m away from the cheetah. The moment the cheetah started running, antelope took off running. The cheetah ran at an average speed of 1200 m per minute, and the antelope 700 m per min. In how many seconds was the cheetah able to catch up
- Average speed The car drove from city A to city B at 40 km/h and back to city A at a speed of 80 km/h. What was the average speed of the car?
