1. The problem statement, all variables and given/known data The only force acting on a 2 kg object moving along the x axis is shown. If the velocity Vx is 2 m/s at t=0, what is the velociity at t=4 s ? 2. Relevant equations P= mv 3. The attempt at a solution Area under the curve is the Impulse, which is Pf - Pi and it's equal to 4 That indicates that p at t=4 - p at t=0 = 4 However, given that v at =0 is 2 By the sub. of the formula we get that P at t=0 is 4 and therefore P at t=4 is 0 Is that Correct ?
