i just want to know what does these problems mean exactly:
first:
an experimental vehicle slows down and comes to a halt with an acceleration whose manitude is 9.80m/s². after reversing direction in a negligible amount of time, the vehicle speeds up with an acceleration of 9.80 m/s². other than being horizontal.
what doesn the red sentence mean
second:
two objects are thrown vertically upward , first one, a bit later, the other.is it possible that both reach the same maximum height at the same instant?
q: do we consider that there is the same intial velocity or different initial velocity?
