A 1450 kg car drives towards a 60 kg shopping cart that has a velocity if -1.2m/s toward the car. The two objects collide, giving the car a final velocity of 5.13 m/s, and shopping cart a velocity of 11.75 m/s

false

because it does not have the potential to be entirely used up

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

im pretty sure its b
