Impulse=Force*Time interval
=30*4=120Ns
To get the impulse, you multiply the time times the force.
The marble moved 30 cm north in 6 seconds.
after 30 seconds the temperature of the water is 19 degrees.
a max speed of 290kmh if you form you self lie a bullet but if you lie out 200kmhAnswer:There is no specific speed for free fall. It is dependent on many factors including the local attraction of gravity, air density, cross sectional area presented to the air flow and mass of the falling object. As a result cats can fall from tall buildings and not be hurt while people or ponies are reduced to a red mess.
not strike for another 30 seconds
Put a piece of Ivory soap in the microwave for 30 seconds.
At 30 mph, an object travels about 102.66 feet in two seconds.
Absolutely! If an object has been already traveling for 30 seconds. If you start your watch at 30 seconds, then t = 0 at 30 seconds! The velocity of the object 3 seconds BEFORE you start the watch would then be t = -3 and 3 seconds after you start the watch would be t = 3.
30 meters subtends 100 seconds of arc.I get a distance of 61,879 meters.
IF it started out from rest, then V = a t = (7.8 x 30) = 234 meters per secondin the direction of the acceleration, at the end of 30 seconds.
10 x 30 = 300 metres.
2.38 seconds.
The higher the impulse of a particular motor, the larger and faster and higher it will cause the rocket to travel. Impulse is a term that describes the relative strength of a rocket motor. The impulse of a given engine is found by multiplying the average force that the motor will push with by the number of seconds that the motor will push. Model rocket motors are usually measured using the metric system, where the units of force are "newtons". If a motor pushed with a force of 10 newtons for 3 seconds, this motor would have an impulse of 30 newton-seconds (usually written 30 N-s). This is the same impulse as a motor which pushes with a force of 3 newtons for 10 seconds. When choosing between two motors with the same impulse, the decision to use a shorter duration with higher force or longer duration with lower force, is made based on the amount of drag and the mass of the rocket and other factors, but these factors are usually much less important than selecting the impulse of the engine. In the United States, model rocket motors use a letter desigtation followed by a pair of numbers, such as "B-6-4". The letter describes the approximate impulse of the motor. "A" motors have around 2.5 N-s of impulse, "B"s have twice as much impulse as "A"s, "C"s have twice as much impulse as "B"s etc.
