Heres a word problem i'm having difficulty with.
Velocity of a projectile. The velocity v of a projectile is a linear function of time t that it is in theair. A ball is thrown downward from the top of a tall building. It's velocity is 42 ft per sec after 1 sec and 74 ft per sec after 2 sec. Write v as a linear function of t. What is the velocity when
t = 3.5 seconds?
this problem comes from the linear equation chapter.
i have this to work with
1. v = distance / time
2. t = 3.5 sec
3. m = y2 - y1 / x2 - x1
4. point slope form: y-y1 = m( x-x1 )
5. slope intercept: y = mx+b
but what i have to work with I still dont know how to come up with the soulution can someone please come up w/ the solution. This seems like a good problem to learn for a future physics class that i'll be required to take.
