andriy [413]

Answer:

B. Researching the problem, using information from a variety of sources

Explanation:

First you must create a hypothesis because with out a hypothesis you can’t do the experiment. Then you have to do some research on your problem/ hypothesis from reliable sources. After have your research you can organize your data with a data table or chart. Then when have your research look for the independent and dependent variable and the control. Then you have to make a conclusion based on multiple experimental trials then repeat the experiment and if it ends up different from the first then something is wrong and that means that you did something wrong. Hopefully this helps you :)

A punter drops a 2.0 kg ball from rest vertically 1 meter down onto his foot. The ball leaves the foot with a speed of 18 m/s at
pav-90 [236]

Answer:

Explanation:

Given

mass of drop m=2 kg

height of fall h=1 m

ball leaves the foot with a speed of 18 m/s at an angle of 55^{\circ}

Velocity of ball just before the collision with the floor

u^=2gh

u=\sqrt{2gh}

u=\sqrt{2\times 9.8\times 1}=4.42 m/s

Impulse delivered in Y direction

J_y=m(v\sin (55)-(-u))

J_y=2(18\sin (55)+4.42)

J_y=38.32 kg-m/s

Impulse in x direction

J_x=m\times v\cos (55)

J_x=2\times 4.42\cos (55)=20.646

J_{net}=\sqrt{J_x^2+J_y^2}

J_{net}=\sqrt{(38.32)^2+(20.64)^2}

J_{net}=43.52 kg-m/s

at an angle of \tan \phi =\frac{J_y}{J_x}=\frac{38.32}{20.64}

\phi =tan^{-1}(1.856)

\phi =61.7^{\circ}
