Car will only accelerate to 5-10 miles per hour..

What is your question?

I was stopped at light.. When it was my turn to go.. I accelerated, but my car would not go faster than 5-10 mph.. There was no engine racing or noises and all gages read normal.... Gas pedal also felt firm, but even though I had it pressed to the ground, my speed was only 5 or so... And I tried reverse and it was the same.. No slipping transmission noises or racing rpm's... Just only accelerated to 5+ Mph. ..?
