1. A Cyclist traveling at a speed of 4.2 ms^-1 accelerates at 1.1 ms^-2 in a time of 7.4 seconds. What is the distance travelled?


2. Homework Equations ?



3. The Attempt at a Solution : The answer is 61m but i don't know how to get that answer
 
Physics news on Phys.org
I would expect you to have seen [itex]s(t)=\frac{1}{2}at^2+v_0t+s_0[/itex]?
 
Yeh thanks i got it
 
When i was doing it i was squaring the whole of the at instead of just the t
 
I see. You should really put that in the relevant equation section, that way people reading this forum could have seen what went wrong right away.
 
Yh sorry this was my first post but thanks anyway
