Homework Statement A 500kg truck collides head on with a 400kg car. They stick together and continue traveling west at 6.00 meters per second. The truck initially travels at 13.0 meters per second. Calculate the impulse and force for the car given that the time of impact was 0.6 seconds. The...

I'm not sure what that formula is, will it help me solve for velocity? These are IB questions, not sure if that makes a difference.

I could use Vx=Vox+at but I don't know what Vox is.

Ok then how do I use this to find the magnitude and direction of velocity?

Isn't the velocity of y zero? So then it would be (0)(1.55) which is zero, right?

I think the time is how long it was in flight, I'm not sure if this is correct or if I was even supposed to solve for time. I used this equation: Δy=Vyt + 0.5αyt^2 12=0.5(-10)(t^2) and used this to solve for t

Sorry, s stands for seconds. Could you explain how to solve the problems?

1. A soccer ball is kicked so that it has a range of 30m and reaches a maximum height of 12m. What velocity (magnitude and direction) did the ball have as it left the footballer's foot? I used the equation to solve for time and got 1.55s. I'm not sure if air resistance is involved, we never...
