Plz help me i don't understand this question its a science question also the second page too thanks

An RC car is carrying a tiny slingshot with a spring constant of 85 N/m at 0.2 m off the ground at 5.6 m/s. The sling shot is pulled back 3.5 cm from a relaxed state and shoots a 25 g steel pellet in the same direction the car is moving. What is the velocity of the steel pellet relative to the ground as it leaves the sling shot Which relation is a function?{(1, 1), (2, 2), (1, 2), (1, 2)}{(1, 2), (2, 3), (3, 2), (2, 1)}{(1, 4), (2, 3), (3, 2), (4, 1)} {(4, 2), (3, 3), (2, 4), (3, 2)} Select all the expressions that are equivalent to 4x + 82(2x+4)2(x+4)4(x+1)4(x+2)2(2x)+2(4) These mechanoreceptors would be activated if your little brother poked you in the arm while you were trying to nap.
