A 400g model rocket is on a cart that is rolling to the right at a speed of 4.0m/s. The rocket engine, when it is fired, exerts an 7.0 N thrust on the rocket. Your goal is to have the rocket pass through a small horizontal hoop that is 15m above the launch point.

The answer is 0.45359237. We assume you are converting between kilogram and pound. You can view more details on each measurement unit: kg or lb. The SI base unit for mass is the kilogram. 1 kilogram is equal to 2.20462262185 lb. Note that rounding errors may occur, so always check the results.
Description: The kilogram is the base unit of mass in the International (SI) System of Units, and is accepted on a day-to-day basis as a unit of weight (the gravitational force acting on any given object). The kilogram is almost exactly equal to the mass of one litre of water.Definition: The kg is defined as being equal to the mass of the International Prototype of the Kilogram (IPK), a block of platinum-iridium alloy manufactured in 1889 and stored at the International Bureau of Weights and Measures in Sevres, SÃ¨vres. francehe kg is defined as being equal to the mass of the International Prototype of the Kilogram (IPK), a block of platinum-iridium alloy manufactured in 1889 and stored at the International Bureau of Weights and Measures in Sevres, SÃ¨vres. france
