A problem involving Force in terms of time???? 1. The problem statement, all variables and given/known data There is a body of 3 kg which is moving to the right with a velocity of 10 m/s. A force of 6 N/s2t2 is applied on the body to the left. How much distane will the body have travelled from t=0 when its velocity is 0 m/s? 2. Relevant equations I think they should be F=ma , dv/dt = a, ds/dt = v 3. The attempt at a solution F=6t2 So by newton's second law, F=3(2t2)=ma so i got a = 2t2 Integrating this, i got v=t3+C and s=t4/4 Now i thought initial velocity will be -10m/s which i put in C and V=0 so, 0 = t3-10 or t=2.31 seconds I have no clue what to do after this. I thought i'll substitute the value of t in the equation with s in it, but some how i don't think its correct. And i don't have any answers to check my solution. please help..
