Vf =Vi + at
Vi =Vf - at
= 34 - 15•13
= - 161 m/s :/

I wish there were provided answer choices. Hope this helped
Explanation:
Momentum before collision:
(2 kg) (4 m/s) + (5 kg) (-3 m/s) = -3 kg m/s
No external forces act on the balls, so momentum is conserved. Therefore, momentum after collision is also -3 kg m/s.
The most recent NASA mission on Mars is Mars Science Laboratory. Its key component was Curiosity rover.
Rover has celebrated his first landing anniversary yesterday (Martian year, that is 687 Earth days).
Curiosity managed to find traces of water on Mars, so it's possible that there used to be some life on Mars.
Since landing Curiosity moved only about 5 miles form the landing site (it suffered wheel damage).
