I need help on this one homework problem.
A 747 jetliner lands and begins to slow to a stop as it moves along the runway. If its mass is 3.50 x 10^5 kg, its speed is 27.0 m/s, and the net breaking force is 4.30 x 10^5 N,
a) what is it speed 7.50s later
b) How far has it traveled in this time?
I don't know what equation or formula to use. I also don't know how to relate the force into the problem. The only thing that I know is the accerleration is zero because the jet is breaking.
Can someone please help me on what equation I should use to slove for the answer,
