A particle is moving at some constant speed. Use the following information to answer the following questions.
s(t)=100/t©÷+12; t¡Ã0; see represents feet and t represents seconds
a)Find the velocity and acceleration equations for this particle.
b)When is this particle at rest?
c) On what interval(s) is this particle speeding up?

I cannot interpret your symbols
100/t©÷+12; t¡Ã0
Can you think of a better way to type that equation?
