thanks. i was able to figure out the prob. j/w can you clear me up on graphs of motion? i am a bit confused on how to read them.

in the problem, there is no M stated.

pfinal = pintial + the net force * the change in time.

LaTeX Code: v_y should decrease over time.

i've tried dividing the location of the ball by the 0.4 seconds. it was wrong. I thought of next to multiply the location by 0.4. but I am not sure if that is correct. i think there is something that needs to be done about "The ball's speed is low enough that air resistance is negligible".

Homework Statement A ball is kicked from a location < 7, 0, -6 > (on the ground) with initial velocity < -9, 15, -3 > m/s. The ball's speed is low enough that air resistance is negligible. What is the velocity of the ball 0.4 seconds after being kicked? (Use the Momentum Principle!)...
