EXTREMELY URGENT! I'm in a timed math test atm, and I need answers for lots of questions! Look at the pictures posted, ignore my answer, as I am not confident in it, I just dont have time to leave the questions blank

I have many more so if you could be on stand by notice that would be greatly appreciated

Acar with a mass of 600 kg is traveling at a velocity of 10m/s. how much kinetic energy does it have?

3-12. write each answer with a reasonable number of figures. find the absolute uncertainty and percent relative uncertainty for each answer. (a) [12.41 (±0.09) + 4.16 (±0.01)] x 7.068 2 (±0.000 4) =? (b) [3.26 (±0.10) x 8.47 (±0.05)] - 0.18 (±0.06) =? (c) 6.843 (±0.008) x 104 + [2.09 (±0.04)- 1.63 (±0.01)] =?

If a || b and e || f , what if the value of y ?
