- Doug biked
Doug biked 5 1/4 miles in 3/4 of an hour. What is his average speed? - A filter
It is a pool with a volume of 3500 liters. The filter filters at 4m cubics per hour. How many minutes would it filter the entire pool? - Cheetah vs antelope
When the cheetah began chasing the antelope, the distance between them was 120 meters. Although the antelope ran at 72 km/h, the cheetah caught up with it in 12 seconds. What speed was the cheetah running? - Sewerage
A heavy rain came onto a football pitch with dimensions 110 m x 70 m and during 15 minutes water fell to a height of 80 mm on each m². The pitch is constructed so that it is drained and water can flow away through 4 channels, each with an internal cross-s - Bus speed calculation
A bus driver on a route between two neighboring villages travels at an average speed of 70 kilometers per hour and takes 1/2 hour. At what speed must he goes if he is 10 minutes late and wants to get to the neighboring village on time? - Two ships
Two ships sailed from Venice - a cargo speed of 10 knots and a ferry speed of 18 knots. When will the ferry catch up with the cargo ship if it sailed 10 hours later? - Race car loss
Two race cars passed the finish line at a speed of 216 km/h at a distance of 0.003 s. Express the loss of the second in centimeters. - Cyclists and walkers
A group of tourists started at 8:00 at a speed of 4 km/h walk. At 10:30, another group started on a bike and caught up with a group of tourists at 10:50. What was the average speed of cyclists? - Two cylinders
There are two cylinders, one with oil and one with an empty oil cylinder, with no fixed value assumed infinitely. We are pumping out the oil into an empty cylinder with a radius =1 cm, height=3 cm, rate of pumping oil is 9 cubic centimeters per sec. We ar - Two ports From port A on the river, the steamer started at an average 12 km/h speed towards port B. Two hours later, another steamer departed from A at an average speed of 20 km/h. Both ships arrived in B at the same time. What is the distance between ports A and B
- A hammer
A hammer weighing 500 g hits the nail at a speed of 3 m/s. What is the average force acting on the nail, which penetrates the board to a depth of 5 cm? - Energy on impact
A stone weighing 200 g falls in a free fall for 3 s. Find its kinetic energy on impact. - Aircraft kinetic energy
The 150t aircraft takes off at a speed of 288 km/h and, after a while, reaches a speed of 900 km/h. Determine the change in the kinetic energy of the aircraft. - Kinetic energy
A car traveling at a speed of 25 km/h increased the speed to a) 75 km/h b) 100 km/h when exiting the highway. How many times has its kinetic energy increased? - Hammer fall height From what height does a hammer weighing 200 kg fall if its initial potential gravity was 6 kJ?
- Vehicle meeting calculation
The motorcycle left Děčín at an average speed of 40 km/h. At the same time, a passenger car from Prague drove towards him at an average speed of 80 km/h. The distance from Prague to Děčín is about 100 km. How long and at what distance from Děčín will both - Car cyclist pursuit Behind a cyclist traveling at an average speed of 20 km/h, he left the same place 2 hours later than a passenger car at an average speed of 60 km/h. How long and at what distance will the passenger car catch up with the cyclists?
- Where and when
The truck left Kremnica at 11:00 h at a speed of 60 km/h. At 12:30 h, the passenger car started at an average 80 km/h speed. How many kilometers from Kremnica will the passenger car reach the truck, and when? - Positional energy What velocity in km/h must a body weighing 60 kg have for its kinetic energy to be the same as its positional energy at the height of 50 m?
- Cyclist speed observation
The observer sits in a room 2 m from a 50 cm wide window. A road runs parallel at a distance of 500 m. What is the cyclist's average speed on this road when the observer sees him at 15 seconds?
