- The speed 2
The speed of an electric locomotive is 90 km/h. Express this speed in m/s. - Tourist route time
How long would a tourist walk the route if he measured 24.9 cm on a map with a scale of 1:25000? The marching speed is 4 km/h. - What power 2
What power has a pump output to move 4853 hl of water to a height of 31 m for 8 hours? Comparing the power generated by the pump vs. the power generated by the motor, which is more efficient? Which pump or motor generates more pollution if, for every watt - Observatory and aircraft
The aircraft flying towards the observatory was aimed at a distance of 5300 m at an elevation angle of 28º and after 9 seconds at a distance of 2400 m at an elevation angle of 50º. Calculate the distance the plane has flown in this time interval, its spee - Tunnel passage time
The Branisko tunnel has a length of 4975 m. How long will a car pass through the tunnel if the speed limit is 80 km/h? - The MRT train The MRT running from Taft to North Avenue has a starting velocity of 60 km/hr. After a malfunction, the brakes failed, making the train run at a velocity of 80 km/hr. What is the acceleration rate if the time for velocity change is 5 seconds?
- A cyclist
A cyclist rides for 30 minutes on a style road to the top of a mountain. Down there, the road goes downhill. Its uphill speed is 20 km/h and 60 km/h downhill. The distance from the mountain's summit to its destination is 30 km. Calculate the average speed - Storm distance sound
The sound travels at a speed of 1 km in 3 seconds. If the thunder is heard 12 seconds after the lightning, what distance is the storm? - Car kinetic energy
The car weighs 1850 kg and increases its speed from 27 to 81 km/h. How much has its kinetic energy increased? - Starting The aircraft has a take-off speed of 310 km/h, a take-off weight of 16.5 t, and uses a 2 km take-off runway. Its cruising speed is 880 km/h and cruising altitude is 10 km. a) Determine the aircraft's acceleration during take-off and the take-off time. b)
- Airplane wing pressure An airplane flies at a speed of 920 km/h at an altitude of 11 km above the surface of the Earth, where the air density is p = 0.36 kg/m³. Determine the pressure difference above and below the plane's wing if the top of the plane is 10% longer than the bot
- Power during takeoff
The aircraft weighing 3.5 tons will disembark 1 km in 1 minute after takeoff and reach a speed of 290 km/h. Find the average power of its engines during this time. - Pump power
Determine the pump power if: I pour 3 m³ of water from the tank in 120 seconds with a hose. The height of the hose mouth above the tank is 1.5 m. The water's speed from the hose outlet is 20 m/s. - Janka Katka meeting
Jane and Kate live in villages 16 km away. They agreed to meet precisely halfway. Jane was driving at a speed of 4 km/h. Kate came out 30 minutes later. At what speed must Kate drive to fulfill the agreement? - Athlete cyclist finish The athlete ran on a 10 km route at a speed of 5 m/s, 10 minutes after him. A cyclist drove at a speed of 30 km/h. Who will be at the finish first (A or B)?
- Scooter distance directions
Kate and John set out on their scooters at the same time. Kate rode at a speed of 4.5 km/30 min, and John rode at a speed of 4 km/20 min. a) How many meters did they travel in 2 minutes if they went in opposite directions? b) How far apart were they when - Stair climbing performance
A person weighing 50 kg can climb 15 stairs. One step is 18 cm high. Determine a person's performance when: a) slowly climbing the stairs if it took him 13 seconds b) going down the stairs slowly if it took him 10 seconds c) quickly climbing the stairs if - 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
- 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. - 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?
