Students perform an experiment with the goal of finding the relationship between the force applied to an object and the time required to stop the object. During the experiment, a student jumps and lands on a large sensor that measures the magnitude of the force exerted on the scale and the time it takes to bring the student to rest. During the first trial, the student jumps and lands on the sensor while keeping their legs perfect straight. Which of the following describes a proper change in procedure to correctly find the relationship between the force applied to an object and the time required to stop the object?A. Jump to the same height and land with knees bent. This will increase the time to bring the student to rest and decrease the magnitude of the force. B. Jump to the same height and land with knees bent. This will decrease the time to bring the student to rest and increase the magnitude of the force. C. Jump higher and land with knees bent. This will increase the time to bring the student to rest and decrease the magnitude of the force. D. Jump higher and land with knees bent. This will decrease the time to bring the student to rest and increase the magnitude of the force. E. Jump higher and land with legs straight. This will increase the time to bring the student to rest and decrease the magnitude of the force.

The statement that effectively describes the change in the process to determine the association between the force that has been exerted on the object and the time needed to stop would be:

A). Jump to the same height and land with knees bent. This will increase the time to bring the student to rest and decrease the magnitude of the force.

As per the question, the bending of knees and attempting to jump at the same height would assist in enhancing the time that will be required to bring the student in the state of rest while a reduction in the force's magnitude.The reason behind this is that landing with bent knees increases your the time of impulse and therefore, more time will be required to bring him to rest i.e. mv = 0.

Thus, option A is the correct answer.

Answer from: sonnekaustin60

land with leg bent to increase the time needed to bring the student to rest and decrease the magnitude of the force.

Explanation: from Newton's second law, F = (mv - mu)/t

Bringing the body to rest means mv is zero I.e

F = -mu/t

Bending the knee increases impulse time

from the equ. one can see that increasing the time will cause the magnitude of the force to decrease

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.
