Physics

At t = 0, one toy car is set rolling on a straighttrack with initial position 14.0 cm, initial velocity -3 cm/s, andconstant acceleration 2.30 cm/s2. At the same moment,another toy car is set rolling on an adjacent track with initialposition 8.5 cm, initial velocity 6.00 cm/s, and constant zeroacceleration.

(a) At what time, if any, do the two cars have equal speeds?(Enter NA if the cars never have equal speeds.)


(b) What are their speeds at that time? (Enter NA if the cars neverhave equal speeds.)
cm/s

(c) At what time(s), if any, do the cars pass each other? (If thereis only one time, enter NA in the second blank. If there are twotimes, enter the smaller time first. If they never pass, enter NAin both blanks.)



(d) What are their locations at that time? (If there is only oneposition, enter NA in the second blank. If there are two positions,enter the smaller position first. If they never pass, enter NA inboth blanks.)
