Question

-3.5n < 1.4

Answer 1

same process as before. try it.

Answer 2

So I have to divide each side by -3.5 and I get
N<(1.4/-3.5)

Answer 3

Ok I dont know if this is right but I got N<.04

Answer 4

you are on the right track, but you forgot to flip the < to > since you divide by a negative number

Answer 5

err -.04

Answer 6

ok so N>.04

Answer 7

n>-.04

Answer 8

ok.. Thanks

Answer 9

welcome

Answer 10

newton second law:

F=m*a
-3.5 N = 1.4 kg * a (the minus sign because F is in the opposite direction of motion.

a= - 2.5 m/s^2

Very important formula:

Vfinal^2 - Vinitial^2= 2 * a * distance traveled

distance traveled= -7.5^2/ (-2.5*2)
distance traveled= 11.25m
