45.2 Km/h into m/s

30.5 m/s into km/h

- A car moves at 18 m/s [E] and experiences a displacement of 450 m [ E]. How long did this trip take?

How can I solve these?

- A batmobile is moving with a constant velocity toward the north. Batman decides to slow down. In what direction will his acceleration be?

-An airplane accelerates from 82 m/s [E] to 95 m/s [E] in 6.5 seconds.

>Calculate the acceleration of the airplane.

>Write a sentence that descrives this motion

-A speedboat accelerates at 4.80 m/s(squared) [N] and reaches a final velocity of 32.6 m/s(squared) [N] in 2.31 s. What was the initial velocity of the boat?

If you guys know any websites that can help me look at motion formulas like velocity, displacement, acceleration, vectors.....scales.... explaining how to do them please post

Thanks
