3. after some time of sliding iron man with an initial forward velocity of +4.42 m/s accelerates uniformly at -0.75 m/s2. how long does it take for him to come to a stop?
i was not there can not tell you.
a. 198.9 s
b. 3.31 s
c. 5.9 s

Which of the following explains why it took so long for the public to accept the negative health effects of smoking? a)people were waiting for counter reasons, and those were presented.b)scientists had not completely finalized their results, which took 30 years.c)cigarettes were cheaply available and media channels were very inefficient.d)cigarette manufacturers were trying hard to bring an alternative into the market

What is the final velocity of the initial velocity of 25 and -50?

Light from the sun reaches the earth in 8.3 minutes. the velocity is 3.00 x 10^8 m/s. how far is earth from the sun? i know how to get to d = (3 x 10^8 m/s)(498 sec). i just don't know how to get from there to the answer being 1.5 x 10^11 m.
