You should be familiar with the impulse/momentum equation. Or just use F_net=ma. Give it a try.rcmango said:Homework Statement
A 41 kg hatch is thrown at a speed of 215 m/s and is immediately stopped once it hits something that lasts for a time of 5.6 ms.
So What is the magnitude of the average net force that acts on the hatch during the point that its hitting something?
Homework Equations
The Attempt at a Solution
where do i start?
please help me with this one.
The mass is given. What's the equation to use to find acceleration when the velocity change and time are known?rcmango said:okay, so if i use the formula of F_net=ma
i don't know the net forces (Newtons)
i don't know the mass or the acceleration (m*a)
i do know the velocity and the time.
so must i use an equation to find the acceleration? so I'm closer to my answer?
what do i need to solve for next?
watch units, the change in v is in m/s, and t is given in milliseconds(i.e., t =.0056 seconds).rcmango said:the formula is a = chng velocity / chng time
so a = 215 / 5.6 ?
Magnitude is a measure of the strength or size of a force. In net forces problems, magnitude refers to the numerical value of the force, typically measured in Newtons (N) or pounds (lbs).
To calculate the net force in a problem, you need to add all of the individual forces acting on an object together. If the forces are acting in the same direction, you can simply add them. If they are acting in different directions, you will need to subtract the smaller force from the larger force to determine the net force.
Net force refers to the overall force acting on an object, taking into account all of the individual forces. If the net force is not equal to zero, the object will experience a change in motion. A balanced force, on the other hand, refers to two or more forces that are equal in magnitude and opposite in direction, resulting in a net force of zero. This means the object will remain in a state of rest or continue moving at a constant velocity.
The magnitude of a force directly affects an object's motion. The larger the magnitude, the greater the impact on the object's motion. A larger force will cause the object to accelerate more quickly or change direction more drastically, while a smaller force will result in a slower or less significant change in motion.
Yes, the direction of a force can have a significant impact on the net force on an object. When multiple forces are acting on an object, their directions must be taken into account in order to accurately calculate the net force. Forces acting in the same direction will add together, while forces acting in opposite directions will subtract from each other.
