- Force meter
We put the statuette on the force meter, which showed a value of 25 N. Then, we placed it on the force meter, completely immersed in the water. The force meter showed a value of 17 N. What is the statuette's volume?
- Acceleration 2
If a car traveling at a velocity of 80 m/s/south accelerated to a speed of 100 m/s east in 5 seconds, what is the car's acceleration? Using Pythagorean theorem
- Traffic collision
When investigating a traffic accident, a policeman found that the driver stopped the vehicle immediately after the accident by constantly braking on a 150 m track in 15 seconds. Do you approve that the driver exceeded the village's permitted speed (50 km/
- The tram
The tram is moving with acceleration a = 0.3m/s2. How long will it pass the first meter of the track? How long does it take 10 meters? What is its speed at the end of the 10-meter track?
- Compressive 4914
At what depth does a hydrostatic compressive force of 3.2 MN acting on an area of 30 m² arise in mercury? (mercury density is 13,500 kg/m2)
- Forces on earth directions
A force of 60 N [North] and 80 N [East] is exerted on an object weight of 10 kg. What is the acceleration of the object?
- Compressive 4894
At what depths does a hydrostatic compressive force of 3 kN act at a depth of 30 m in water?
- Hydrostatic force
What is the hydrostatic force applied to an area of 30 cm² in the water at a depth of 20 m? (Water density is 1000 kg/m3)
- Runners 4857
Two runners run on a 3200m oval track, one running at 12 km/h and the other at 8 km/h. How long does it take for the first runner to finish the second one?
- Megapascals
What is the area of cross-section of the piston if the force of 300 kN produces a pressure of 5 MPa?
- Accelerating 4813
When accelerating from 0 to 100 km/h in 9.3 seconds, what distance will the car travel?

- Gasoline
How many liters of gas is in the tank if its weight is 15.4kg? The specific density of gasoline is 770kg/m³.
- Two aircraft
From the airport will start simultaneously two planes, whose flight tracks are perpendicular to each other. The first flying speed of 680 km/h and the second 840 km/h. Calculate how far the aircraft will fly for half an hour.
- Time clock
What are the angles of the hour hand and the minute hand if it is 0:40?
- Kilometers 4614
The car is traveling at 130 km/h. a / How many hours will it help the car drive for kilometers? b / How many kilometers will the car travel in h hours?
- Projectile 4611
A projectile weighing m1 = 0.01 kg is fired at a velocity v1 = 800 m * s-1 from a rifle weighing m² = 4 kilograms.
- Prescribed 4579
The racing ball for men has a prescribed weight of 7250g. It is made of iron. How does its diameter change if we make it from lead? The density of iron is 7.8 g / cm cubic, and the density of lead is 11.3 t / m cubic.
