Use the impulse equation!
FT = m(Vf - Vo)
F(10) = 1000(15 - 0)
F = 1500 Newtons

What force is needed to move a 3000 kg truck at a rate of 2 meters per second squared?
Force = mass * acceleration Force = (3000 kg)*(2 m/s^2) = 6000 Newtons ---------------------- ( that is 6000 times the force needed to push in a doorbell, on average )
What is the magnitude of the net force needed to bring a 2175 kg car to rest from 24.2 meters per second in 7.4 seconds?
approximately 7000 newtons
What is the force acting on 2800 kg truck if its slows down from 60 meter per secs. to 35 meter per secs. in 6 seconds?
(-)11,666.67 N. To calculate this, you need to use the impulse-momentum principle, whereby the change in momentum is equal to the force multiplied by the time over which the force is applied. The change in momentum here is the final speed x the mass - the initial speed x the mass. Then divide the answer by the time (six seconds) and the answer will be the force applied (in this case the answer is negative as the force is applied in the direction opposite to the direction of the truck's motion.)
How much force is needed to stop a car that weighs 500kg and is going at 30 meters per second?
Depends on the amount of time we are given to stop the car. Force = mass x acceleration If we are given 1000 000 seconds to stop the car Force = 500kg * 30/1000000 = 0.015N
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
What type of force is needed to change the of objects?
force of compression
What type of force is needed to change the velocity of object?
force of compression
What is needed to change its speed or direction?
Force
Which machine changes the direction of force needed to do a task without changing the size of force needed?
A pulley can do that.
What type of force is needed to cause a change in an object's motion?
A force is needed to cause a change in an object's motion. This force can be a push or pull exerted on the object, causing it to accelerate, decelerate, or change direction.
What is needed to change an objects motion?
an unbalanced force
A change in momentum or impulse can be found by the product of mass and the change in velocity. If a force of 20 N is applied for a 2 seconds on an object. What is the impulse given to the object A) 0?
The impulse given to the object is 40 Ns (Newton-seconds). This is calculated by multiplying the force of 20 N by the time of 2 seconds. Impulse is the change in momentum experienced by an object, and it is equal to the force applied multiplied by the time over which the force is applied.
What force is applied to an object if the duration of the force is 8 seconds an the object is uniformly accelerated from rest to 6 meters per second?
You can't tell from the information given. All you know is that the average acceleration is (change in speed) divided by (time for the change) = (6/8) = 0.75 meters per second2. The force required depends on the mass of the object to be accelerated by the force.
A force is needed to change the motion of an object?
Yes, an unbalanced force is needed to change the motion of an object.If an unbalanced force does not act on an object it will continue to maintain its state of motion (either in motion or at rest), not considering the effect of frictional force. This is basically Newtons first law of motion.
Is net force needed to change the speed or direction of moving matter?
Yes, a net force is needed to change the speed or direction of moving matter. Newton's first law of motion states that an object will remain in its state of motion unless acted upon by an external force. When a net force is applied, it can accelerate the object, decelerate it, or change its direction.
The amount of needed to make an object change its depends on the of the object and the required?
. The amount of Force needed to make an object change its motion depends on the Mass of the object and the Force required
Which type of machine change the direction or amount of force needed to do work?
Simple
