I am having trouble about what formula  I should use

anonymous · Answer

any tips?

anonymous · Answer

look at your givens
t=11 seconds
Vf=70.0 m/s
Vi=0m/s --> since they said that it starts from REST

for this one, you just simply use the formula for acceleration $\Large a= \frac {v_f-v_i}{t}$

anonymous · Answer

after this problem, would you have the time to help me out with more physics

problems?

anonymous · Answer

i'll try because, i also have physics assignments ^.^

anonymous · Answer

so the acceleration of the object is simply 70/11?

anonymous · Answer

yes, don't forget the direction

anonymous · Answer

the direction is positive, right?

anonymous · Answer

yes
