What else can I help you with?
Select all what that are equal to an impulse of 20 units.?
An impulse of 20 units can be represented by various combinations of force and time. For example, a force of 20 units applied for 1 second results in an impulse of 20 units (20 N × 1 s = 20 Ns). Similarly, a force of 10 units applied for 2 seconds also gives an impulse of 20 units (10 N × 2 s = 20 Ns). Therefore, any combination of force and time that multiplies to 20 units qualifies as equal to an impulse of 20 units.
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.)
What factors are used to calculate impulse?
impulse= the change in momentum or force multiplied by time
What is the impulse needed to stop a 9 kg bowling ball moving at 4 meters per second?
Are you sure that's all there is to the problem? I may be wrong or missing something, but impulse deals with time so we'd need to know how much time we have to stop the ball, i.e. 10 seconds or possibly 3 meters... Divide 36 by how much time you have in seconds to get the force required and don't forget that the force is negative.
What is the equal to an impulse of 15 units?
An impulse of 15 units is equal to the change in momentum of an object. Impulse is calculated as the product of force and the time duration over which the force acts. Therefore, if an impulse of 15 units is applied, it means that the object's momentum has increased or decreased by 15 units as a result of that force over the specified time.
Is the impulse produced by a larger force always greater than the impulse created by a smaller force?
I believe the answer is no. The impulse produced is also time related. Impulse force is measured as dp/dt. Therefore a smaller force produced for a very quick time could produce a larger impulse than a large force over a longer time.
Does large force always produce a larger impulse on an object than a smaller force does?
Not necessarily. Impulse depends on both the force applied and the time over which it acts. A smaller force acting for a longer time can produce the same impulse as a larger force acting for a shorter time.
Mariela used 45 N of force to stop a cart that was about to roll into Jamilett. It took Mariela 12 seconds to do so. What was the impulse acting on the cart?
die
What is a direction of impulse?
impulse is equal to force which is acting on the body and ti me in small interval which is equal to momentum.so impulse is equal to change in momentum and direction of impulse is consider the direction of force and change in momentum.
The product of a force acting on an object and the duration the force acts upon the object is called?
The product of a force acting on an object and the duration the force acts upon the object is called impulse. Impulse is a vector quantity that represents the change in momentum of an object. It can be calculated by multiplying the force applied by the time over which it acts.
What is the impulse of an object that Applies 30 N for 4 seconds?
Impulse=Force*Time interval =30*4=120Ns
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 impulse would occur when the same force of 10 N acts on the cart for twice the time?
The impulse will be twice as large, at 20 Ns, due to the force acting for a longer duration. Impulse is the product of force and time, so increasing the time the force is applied increases the impulse.
How to calculate impulse in a physics problem?
To calculate impulse in a physics problem, you multiply the force applied to an object by the time over which the force is applied. The formula for impulse is Impulse Force x Time. Impulse is a vector quantity and is measured in Newton-seconds (Ns) or kgm/s.
To have the greatest impulse there should be?
there should be a large force acting for a long time. D.
What is meant by impulse?
Impulse is the change in momentum of an object. It is calculated by multiplying the force applied to an object by the time over which the force is applied. Impulse is a vector quantity and is measured in units of Newton-seconds (Ns) or kg m/s.
When impulse will be zero?
An impulse will be zero when the force acting on an object is zero or when the force is applied for a very short period of time. In other words, when the change in momentum of an object is zero, the impulse will also be zero.
