How much force is needed to lift 70kg box with an 2 minutes per seconds acceleration of the box?
momentum is mass x velocity (p=mv), and velocity is distance divided by time (d/t),
so p=m(d/t)=(70kg)(400m/50s)=560 kgm/s
================================
Answer #2:
If the questioner actually knew what he was talking about when he posted
the question, then the runner's average momentum is
(70 kg) x (400 miles) x(1,609.344 meters/mile)/(50 seconds) = 9.012 x 105kg-m/sec
We can't help but notice that in the question's frame of reference, the runner is
steaming along at 28,800 miles per hour. This arouses our curiosity, but is not
germaine to the problem or to its solution, and we play the hand we are dealt.
Our math and physics are bullet-proof, and we stand by them.

. The amount of Force needed to make an object change its motion depends on the Mass of the object and the Force required
How much force is needed to keep a 2kg object moving?
No force is needed to keep an object moving. An object with no forces on it keeps moving at a constant speed in a straight line. If there is any force acting on it to make it slow down, then you need just enough force to cancel the first one, in order to keep it moving.
What is the planes acceleration if it was 7000 kg and is launched from an aircraft carrier in 2 seconds by a force of 35000 newtons?
The idea here is to use Newton's Law, F=ma. Solving for acceleration: a = F/m. The number of seconds is irrelevant if all you want to calculate is the acceleration.
What is the cause and effect relationships between force and acceleration?
The relationship between force and acceleration is defined by Newton's second law of motion, which states that the acceleration of an object is directly proportional to the force acting on it and inversely proportional to its mass. This means that if a greater force is applied to an object, it will experience a greater acceleration, assuming its mass remains constant. Conversely, if the mass of an object increases, a greater force is needed to achieve the same acceleration.
How CAN altering the mass and acceleration affect force?
Altering the mass will directly impact the force required to achieve a certain acceleration, as described by Newton's second law (F = ma). If the mass increases, more force is needed to accelerate it at the same rate. Similarly, changing the acceleration will also affect the force required, as a higher acceleration will demand more force to overcome inertia and produce the change in motion.
What is the acceleration of an object with a mass of 60 kg?
The acceleration of an object depends on the force acting on it. If a force is applied, the acceleration can be calculated using Newton's second law: acceleration = force / mass. More information about the force acting on the object is needed to determine its acceleration.
What is the Acceleration of Fnet100N with a velocity of 20ms in 5 seconds?
To calculate the acceleration, you need to divide the net force by the mass.
How much force is needed to accelerate a 66 kg skier at 2 sec?
To calculate the force needed to accelerate the skier, you need to know the acceleration. If the acceleration is not provided, you can use the formula F = m*a, where F is the force, m is the mass of the skier (66 kg), and a is the acceleration. However, without the acceleration value, the force cannot be accurately calculated.
How is newtons seconds law related to gravity?
Gravity exerts a force; the Second Law states that such a force will cause an acceleration, which can be calculated as:a = F/m (acceleration = force divided by mass).
What force is needed to accelerate an object has a mass has Of 10kg?
The force needed to accelerate an object can be calculated using Newton's Second Law, which states that force equals mass times acceleration (F=ma). If the mass of the object is 10kg and the desired acceleration is known, the force required can be calculated by multiplying the mass by the acceleration.
How much force is needed to accelerate a plane?
The force needed to accelerate a plane depends on its mass and the desired acceleration. It can be calculated using the equation F = ma, where F is the force, m is the mass of the plane, and a is the acceleration. This force is typically generated by the plane's engines.
How much force is needed to bring a 3500pound car from rest to a velocity of 48feet per second in to seconds?
Force = Mass x Acceleration Initial speed of car = 0, Final speed = 40 feet/sec in time 2 seconds Acceleration = (v-u)/t = (40 - 0)/2 = 20 feet/sec/sec Force = 3500 x 20 = 70000 pounds/sec/sec
A constant forces of ION pushes a 10 kg box of 10 seconds If the was initially at rest what its speed after 10 seconds?
To determine the speed of the box after 10 seconds, we need to use the formula for acceleration: ( a = F / m ), where ( a ) is acceleration, ( F ) is the force, and ( m ) is the mass. Given that the force is constant and the box starts from rest, we can further use the equation for speed ( v = a * t ), where ( t ) is time. Calculate the acceleration using the force and mass, then use that acceleration to calculate the final speed after 10 seconds.
How much force it needed to accelerate a 25 kg bowling ball at?
The force needed to accelerate a 25 kg bowling ball would depend on the desired acceleration. Newton's second law states that force equals mass multiplied by acceleration (F = ma). If you specify the acceleration, the force required can be calculated using this formula.
Why is force needed?
Force happens when an object of mass is accelerated, and the equation to calculate force is : force=mass/acceleration
An unbalanced force of 30 N gives an object an acceleration of 5. What force would be needed to give it an acceleration of 1?
If a force of 30 N imparts an acceleration of 5 to an object and we desire only one fifth of that acceleration, then we apply only one fifth of that force. Take the 30 N and divide it by 5 and we find that 6 N is the force required to give our test object an acceleration of 1.
How much force is needed to accelerate a 25kg bowling bowl a 2mss?
The force needed to accelerate an object is given by the formula: force = mass x acceleration. For the bowling bowl with a mass of 25kg and acceleration of 2m/s^2, the force required would be 50 Newtons.
