A baseball moving at 20m/s is struck by a bat and moves to the opposite direction at 30m/s. If the impact lasted 0.010s, what was the baseball's acceleration? (Please tell me what formula should I use to solve this)

Question

amistre64 · Answer

prolly a combination of a few of them

amistre64 · Answer

momentum formulas might be useful

amistre64 · Answer

we dont know force, and we dont know mass ... so impulse may not be useful

anonymous · Answer

how do we solve for that?

amistre64 · Answer

i think i got it ...

amistre64 · Answer

$$F=ma;~a=\frac Fm$$
$$I=F~\Delta t=m~\Delta v;~\frac{F}{m}=\frac{\Delta v}{\Delta t }$$

@,@ i dont get it. really. hahaha sorry. i just dont understand physics. we have our mid quarter exams tomorrow in physics and i dont know how to solve for this stuffs

amistre64 · Answer

these formulas would have had to have already been presented to you thru the course of your term

amistre64 · Answer

Newtons second law is:  Force = mass times acceleration;  and mathing that out we get a=F/m

im in my senior year in high school. from philippines

amistre64 · Answer

Impulse, change in momentum is the formula:

Force, times change in time = mass, times change in velocity

anonymous · Answer

our just started last month. i believe this lesson is about vectors.

amistre64 · Answer

it includes vectors yes ... but they are incident to it

amistre64 · Answer

the change in velocity:  20m/s - - 30m/s = 50 m/s

the change in times is given as .01 seconds

50m/s/.01s = 5000m/s^2

anonymous · Answer

so, thats the answer?

amistre64 · Answer

thats the answer i come up with ... if its the correct answer or not might still be up for debate
