- The caravans
At 6:00 in the morning, a caravan set out of the oasis at a speed of 1.5 miles per hour. Two hours later, a second caravan followed her at 2.5 miles per hour. When did the faster caravan run slower? How far from the oasis? - Tractor vs car
Behind the tractor, which was traveling at an average speed of 20 km/h, a car started in two hours and overtook it in 1 hour. At what speed was the car moving? - Car distance
Two opposite cars passed on the way and continued. One car drove 17.5 m in 1 second and the other 15.25 m. How far will these cars be in half an hour? - The stadion
John can run around a circular track in 20 seconds and Eddie in 30 seconds. Two seconds after Eddie starts, John starts from the same place in the opposite direction. When will they meet? - Free fall
How long and at what speed does the body fall to the ground during a free fall from a height of 35 m? - Plane distance
Two planes took off from Prague at one point. The first is flying north at a speed of 420 km/h, and the second is flying east at a speed of 560 km/h. How far apart will they be as the crow flies in 25 minutes of flight? - Rotary motion
Find the orbital time, rotational frequency, and angular rate of the second and minute hands on the watch. - Electrostatic
A proton with mass mₚ = 1.67 × 10⁻²⁷ kg and electric charge e = 1.6 × 10⁻¹⁹ C, initially at rest, is acted upon by a uniform electrostatic field of unknown intensity E. The proton moves in the direction of the field lines and over a path s = 22 cm acquire - Motorbike circuit
On a 2,550 m long circuit, two motorcycles go at such speeds that they meet every minute if they go against each other and run every 5 minutes if they go in the same direction. Find their speeds. - Wave travel time
A plane wave has an amplitude u0 = 40 cm and a frequency f = 10 Hz. The speed of wave propagation through the medium is v = 40 cm/s. At a distance x = 10 cm from the starting point, the wave has an instantaneous deflection u = 15 cm. How long does it take - Shopping meeting
Kate left the store with a heavy purchase at a constant speed of 0.5 m/s. Her brother Michael ran to help her at a constant speed of 3.25 m/s. How many meters did Kate have to walk with her shopping before meeting Michael if the store is 300 m from the ho - Earth rotation
How fast is the place on the Earth's equator moving if the Earth's radius is 6378 km? - Cyclist travel time
The cyclist will travel 22 km in an hour and a half. How long would it take to drive 30 km? - Bus average speed
The bus left from stop A to stop B. The distance between the stops is 3.6 km. The timetable states that he has 3 minutes to cover this distance. At what average speed in km/h would the bus have to travel in order to pass the time interval? - Ball kick speed
The football player kicked a 400 g ball with a force of 480 N during a penalty. How fast did the ball again if it was subjected to an impact force of 0.01 s? - Oscillator deflection
The amplitude of the linear undamped harmonic oscillator is A = 12 cm, and the frequency f = 15 Hz. What is its instantaneous deflection at time a) t1 = 0.02 s, b) t2 = 0.04 s, when it was zero at time t = 0 s? - Snow White transport
The dwarfs dragged Snow White in a coffin from the garden to the house as Snow White with the coffin was heavy. The dwarves pulled her with a speed of 0.2 m/s. The place where Snow White and the coffin were laid was 15000 cm away from the place in the hou - Running pursuit Oldřich ran out of the house at 7.00 at 10 km/h. After 3 minutes, Jerry also ran at 12 km/h. A) what time did Jerry Oldřich finish? B) how many km did each run?
- Athletic oval
On the 400 m athletic oval, two athletes started back to back from the same level. After the starting shot, they both ran away from each other simultaneously. Athlete A ran at 15 km/h, and Athlete B ran at 17 km/h. A) in how many seconds did the athletes - Boy bicycle pursuit
A boy leaves school at a speed of 1 m/s. At the moment, when he is 100 m away from the school, a classmate on a bicycle comes behind him at a speed of 5 m/s. How long and how far does the boy run from school? Solve by calculation and graphically.
