If an object starts out at rest and accelerates to 100 m/s, what is its initial speed?
a. -100 m/s
b. 0 m/s
c. 100 m/s
d. 32 m/s
p.s. I think that the answer is C. Am I right? If not, what is the right answer? Thank you.
No. Sadly, you're not right. The whole problem here is the meaning of a few words. "Starts out"is the same thing as "initial" conditions. "At rest" is the same thing as not moving ... zero speed. So if an object starts out at rest, that says that its initial speed is zero ... choice 'b'.
