Question

Students set up an experiment in which a block is given an initial push on a rough horizontal surface, and the block slides through a photogate. The photogate is used to determine the block’s speed, and the students use a meter stick to measure the distance that the block slides past the photogate before coming to rest. The students repeat the experiment for several trials. For each trial, the block is given a different speed through the photogate. __________ is a scientific hypothesis that can been tested by the data collected by the students.

Answer 1

Hello. That you forgot to put the answer options. The options are:

Students calculate the coefficient of friction between the block and the surface.  

The work done by friction in bringing a block to rest is directly proportional to the initial kinetic energy of the block  

The velocity of the block as it slides through the photogais directly proportional to the force exerted on the block during the initial push  

The power generated is directly proportional to the force exerted on the block.  

Students use the work kinetic energy theorem to calculate the mass of the block

Answer:

The work done by friction in bringing a block to rest is directly proportional to the initial kinetic energy of the block  

Explanation:

The options shown above refer to the scientific hypothesis of the experiment shown in the question.

A scientific hypothesis is characterized by an assumption, a possible solution, that a research can present on a given scientific problem. The hypothesis, in other words, is an assumption that will be declared to be true, or false, after it has been tested through scientific experiment.
