What thrust does a 190 gram model rocket need in order to have a vertical acceleration of 11.0 meters per second squared on earth?

F = m A
m = 0.19
A = 11
F = (0.19) x (11) = 2.09 newtons upward
But there is another force on the rocket = (m g) = (0.19) x (9.8) = 1.862 newtons downward.
The engine also has to cancel this force.
Total engine thrust required = (2.09 + 1.862) = 3.952 newtons.

How do you convert miles per hour squared to meters per second squared?
There are a couple of pieces of information you'll need first. Here they are:-- 1 mile = 1,609.344 meters-- 1 hour = 3,600 secondsNow, take your miles-per-hour number, and multiply it by ' 1 ' a couple of times.(Remember that a fraction with the same thing on the top and bottom is equal to ' 1 '.)(X miles/hour2 ) x (1,609.344 meters/mile) x (1 hour/3,600 seconds)2 = 0.00012418 X meters/sec2Massage this result for a bit, and you discover that if you have enough fuel aboardyour rocket ship to keep pumping along at the acceleration of "1 G", then you'refeeling pretty comfortable inside, even though at the end of the hour, you've justhit 78,974 mph and you're still gaining.Why, at that rate of acceleration, 10% of the speed of light is only 35.4 days away !
What is the acceleration of a rocket ship in outer space that takes 5.0 seconds to increase its speed from 1240 meters per second to 1300 meters per second?
12m/s2 1300m/s-1240m/s = 60m/s =12m/s 5s 5s s 12m/s/s=12m/s2
A rocket ship leaves earth's atmosphere. Its Initial velocity is less than its final velocity. What is this an example of?
Reduced atmospheric drag at higher altitudes, Acceleration due to the thrust of the rocket's engine(s).
What is the speed of a rocket in meters per second?
Military rockets of the 1800s achieved velocities on the order of 100 meters per second. Robert Goddard achieved mach 1 (about 350 m/sec) with his rockets. To escape the gravity of our Earth, a rocket would need to achieve a velocity of about 11,000 m/sec. The X-15 rocket plane achieved a speed of over 110,000 meters per second.
How long to drive 196 miles at 80 mph?
Wow - finally a rocket science question. 196 / 80 = 2.45 hours. However, this does not take acceleration nor deceleration into account.
On what factors acceleration of rocket depends?
The acceleration of a rocket depends on the thrust produced by the engine and the mass of the rocket. A higher thrust will result in greater acceleration, while a higher mass will decrease acceleration. Air resistance can also affect acceleration, with lower air resistance allowing for greater acceleration.
How much force does a 20000 kilograms rocket develop to accelerate 1 mass divided by speed squared?
The force exerted by the 20000 kg rocket can be calculated using Newton's second law: force = mass * acceleration. If the mass being accelerated is 1 kg, and the speed squared is the acceleration value, the force would be 20000 kg * (1 m/s^2) = 20000 Newtons.
What effect does the mass of a rocket have on its acceleration?
A heavier rocket will have a lower acceleration compared to a lighter rocket, assuming the same amount of force is applied. This is because the heavier rocket will require more force to overcome its inertia and accelerate.
A force of 1500 N gives a rocket an acceleration of 2.5ms2 what is the mass of the rocket?
it is 600kg
Why does a rocket takes a lot of force?
A Rocket has a LOT of MASS. Its initial Velocity is ZERO and its final velocity must be approximately 25,000 MPH to get into Orbit. That takes a LOT of Acceleration! FORCE = MASS x ACCELERATION FORCE = 1/2 MASS x V2 (the 2 means squared) Looking at these equations you can see that requiring a High amount of Acceleration, and a LARGE terminal Velocity acting on a HUGE Mass, will require a "lot of FORCE". It is simple Arithmetic!
Acceleration of a rocket is which type of force contact or non contact?
Acceleration of a rocket is due to a non-contact force known as thrust. Thrust is generated by expelling mass from the rocket at high velocities, resulting in a reaction force that propels the rocket forward.
Does a rocket stay the same speed through-out its journey?
No, a rocket does not stay at the same speed throughout its journey. The rocket experiences acceleration as it moves through the atmosphere and then into space. During this acceleration phase, the rocket speeds up until it reaches its desired velocity for the remainder of its journey.
What is the intensity sound of a space rocket?
The intensity sound of a space rocket is calculated based on its acceleration and height.
What is the speed of a rocket that travels 9000 meters in 30 seconds?
what is the speed of a rocket that travels 9000 meters in 12.12 seconds
What is the speed of a rocket that travels 9000 meters in 12.12 seconds-?
A rocket that travels 9000 meters in 12.12 seconds moves at 742.5742 meters/second which is approx 1660 mph
What are some examples for force and acceleration?
A car accelerating when the driver presses the gas pedal - the force applied by the engine causes acceleration. A ball falling towards the ground due to gravity - the force of gravity causes the ball to accelerate downward. A rocket launching into space - the force created by the rocket engines propels the rocket forward, causing acceleration.
