If you guys can help me with this I would appreciate it.
1. A passenger plane lands with a speed of 98m/s and accelerates at -7.0m/(s^2). After how many s does it come to rest?
2. A train moving at 32.0 m/s brakes to a stop in 22.0 s. How far in m did it move while coming to a stop?
3. A rock is thrown upward with a speed of 23m/s. What maximum height in m does it reach before falling back to earth?
I need to know how to do these problems as well as the answers.
Thanks
