Sometimes the weight of a bus is expressed in terms of a gross vehicle weight rating or the maximum amount the vehicle can weigh including cargo and passengers. A girl standing on an aisle of a bus was holding a book. Physics. A constant force is exerted on it for 60.0 s. During the time the force is a. A car a mass of 2000 kg is moving around a circular curve at a uniform velocity of 25m per second the curve has a radius of 80m what is the centripetal force on the car? Where will the book land with respect to the girl's position? b. City Bus. 5. How fast is h How fast is the centre of mass of the system of two vehicles moving? The turbine has an efficiency of 75%. 4. 2.2. (A) 70 km/h (B) 75 km/h (C) 72 kmh (D) 68 kWh A city bus can very in size and weight, depending on the type of bus. 1. 2400 Kilograms (kg) 5291.09429 Pounds (lb) Kilograms : The kilogram (or kilogramme, SI symbol: kg), also known as the kilo, is the fundamental unit of mass in the International System of Units. Why is a jeepney of mass 2000 kg more difficult to stop than a tricycle of mass 1000 kg when both are traveling at same initial speed? 1A) 10 DVS (D) 1.11 MB A bus of 2400 kg is moving on a straight road with a speed of 60 km of 1600 kg is following the bus with a speed of 80 km/h. 2. 1. The weight of the average transit bus is 38,000 pounds. What is the average power developed by the car's engine? A car with a mass of 1500kg starts from rest and accelerates to a speed of 18m/s in 12s. The length of the object was 4050 mm, its width was 2400 mm, and its height was 2557 mm. (a) Calculate the angular velocity the flywheel must have to contain enough energy to take the bus from rest to a speed of 20.0 m/s, assuming 90.0% of the rotational kinetic energy can be transformed into translational energy. A stone used in the sport of curling has a mass of 20.0 kg and is initially at rest, sitting on a flat ice surface. A 26 kW B 35 kW C 1.6 MW D 2.1 MW 20 A wire of diameter d and length l hangs vertically from a fixed point. A scooter has a mass of 250. kg. Buses used to transport students are featured in a variety of classes and types. A scooter has a mass of 250. kg. This free density calculator determines any of the three variables in the density equation given the other two. (b) What velocity is needed for a 2400. kg car in order to have the same momentum? (a) What is the momentum of the car? The average size of a standard city bus is between 35 feet and 50 feet long, and about 8 … In addition, explore hundreds of other calculators including topics such as finance, math, health, fitness, weather, and even transportation. What is the momentum of the car? The wire is extended by hanging a mass M on its end. 6. A bus contains a 1500 kg flywheel (a disk that has a 0.600 m radius) and has a total mass of 10,000 kg. The book fell when the bus suddenly moved forward. Most cities have standard size buses for transportation, while others have "double deckers" or smaller, van-sized buses. Assume that the force of resistance remains constant at 400N during this time. A small car with a mass of 800. kg is moving with a velocity of 27.8 m/s. The Rollover Test The test stand consists of a tip-up platform and a pit with a solid surface (or a tip-up platform on a height of 800 mm over a solid surface). A small car with a mass of 800. kg is moving with a velocity of 27.8 m/s. The mass of the object under discussion (with a supplemental mass) was 610 kg. What velocity is needed for a 2400. kg car in order to have the same momentum? What is the output power of the turbine? 2. The mass flow rate of the water is 2400 kg min –1.
