1. The problem statement, all variables and given/known data Footballer P kicks a ball to another footballer Q with an initial speed of 10 m/s in the direction of unit vector j.Because there is resistance of the field, the ball experiences a retardation of magnitude of 1 m/s^2. By assuming the position of player P as the origin and the movement of the ball as always horizontal and in a straight line find the position of the ball at time , t. 2. Relevant equations 3. The attempt at a solution a= -1 [tex]v=\int a dt=-t+c[/tex] when t=0 , v=10 therefore , v (resistance)= -t+10 so nett velocity of the ball = 10-(-t+10)=t And in vector form , v=t^2 j Am i correct ?
