Ok, i have a question that i need someone to put into simple terms, i kind of understand why, but it would be helpful if someone could explain it more simply. How does the coefficient of friction associated with starting an object's motion compare to the coefficient associated with...

Ohhh... Thanks very much

Thanks for the quick reply hmm... so the first equation would be t = d / 4.2m/s than the 2nd part... would be d = (3.8m/s)(t) + (1/2)(0.15m/s2)(t2) is this right so far?

Ok i just started gr 11 physics, and I am wondering how would you tackle this problem In a long distance race, Michael is running at 3.8 m/s and is 75 m behind robert, who is running at a constant velocity of 4.2 m/s. If Michael accelerates at 0.15 m/s2, how long will it take him to catch...
