These are my answers. Need help. I think I got 80% of it wrong. Mostly trouble on problems 2, 3, 4, 5, 6, and 7

I recommend a standard method for all these problems.

 

Write down a list of all the quantities involved, whether you know them or even need them or not.

There are only 5

 

Initial velocity u =

Final velocity v =

Distance s =

Time t =

Acceleration f =

 

Write the numbers you know (are given) against these you know

 

Then write down all the kinematic equations.there are again 5

 

v = u + ft

s = ut + 0.5ft²

v² = u² + 2fs

f = (v-u)/t

s = 0.5(v+u)t

 

Note that only four of the basic quantities appear in each equation.

 

Find the equation in which you know 3 of these four and calculate the fourth.

 

Fill in the numbers in you table of quantities until you have answered your question.
