A car is traveling at 62 m/s and hits the brakes for 5.6 seconds at rate of -3.5 m/s2 to avoid a collision. What velocity is he traveling now after
applying the brakes?

Can someone explain to me how to do this problem ?

Is it possible to use the energy from two atoms colliding to create a clean burning lasting fuel source with a large amount of force? is it also possible to harness that energy from the two atoms colliding to create a clean energy source that will last for years from just two atoms colliding. is there a possibility to control and store that energy for years but slowly let the energy out enough to power cities cheaper and faster.

Will you chech and finish these for me, because i am stumped with them.
