ok..i got that formula now...so will it be friction=(0.007)(137N) and i get .959

i got it! thank you very much

how will i calculate the friction force and how is it applied?

heres a problem I am stuck on..can someone please help me? a skater has a mass of 78 kg is pushes with a constant force of 137N for a time of 3.3 sec on the ice. the coefficient of friction of the blades against the ice is 0.007. 1. find the skaters acceleration, taking friction into...

i have attached the graph..does it look something like that?

ok...so what happens to the 100m dash?

velocity vs time graph! hola everyone! i have posted this before but not sure it went through...i would appeciated it is someone would help me with it. The world record in the 100m dash set by usain "lighting" bolt at the 2009 world championships, is 9.58s. draw a velocity-vs-time graph of...

hello. I am taking university physics and I am having a difficult time with this problem. can someone help me with it? i really appreciate it very much :) You're testing out a new automobile: starting from rest, you put it through its paces as follows. a. accelerate for 6.3s at 3.9 m s-2...
