1.)To reduce the force of impact you could
a)Extend the duration of the time of impact
b)Decrease the duration of the time of impact
c)Increase the mass of the moving object
=d)None of the above
2.)What happens when you lengthen the duration of impact?
=a)You reduce the force of the impact b)You increase the force of the impact
c)You do not affect the force of impact
on the first, I suspect you are dealing with momentum and impulse. Given an impulse, avgforce*time=impulse, so if one increases time of impact, the avg force decreases.
a) You reduce the force of the impact. Just like extending the duration of a bad joke can make it less painful, extending the duration of impact helps to spread out the force over a longer period of time, reducing the overall impact force. It's like turning a punch into a gentle tap, but without the bruised ego. So, go ahead and embrace the power of lengthening the duration of impact!
The correct answers are:
1) To reduce the force of impact, you could:
a) Extend the duration of the time of impact
b) Decrease the duration of the time of impact
c) Increase the mass of the moving object
Therefore, the correct answer is d) None of the above.
2) When you lengthen the duration of impact:
a) You reduce the force of the impact
1.) The correct answer to reduce the force of impact is a) Extend the duration of the time of impact. When two objects collide, the force of impact depends on the change in momentum during the collision. By extending the duration of the time of impact, you can decrease the change in momentum and therefore reduce the force of impact.
To understand why this is the correct answer, you can think about the equation for momentum: momentum = mass x velocity. When two objects collide, their velocities change. If the collision takes a longer time, the change in velocity is smaller and therefore the change in momentum is smaller. According to Newton's second law of motion, force is equal to the change in momentum divided by the change in time. So, by extending the duration of the time of impact, you decrease the change in momentum and therefore reduce the force of impact.
2.) When you lengthen the duration of impact, the correct answer is c) You do not affect the force of impact. The force of impact depends on the change in momentum, not the duration of impact. By lengthening the duration of impact, you do not change the amount of momentum transferred during the collision. Therefore, the force of impact remains the same.
