A car starts from rest and travels for 5.0 s with a uniform acceleration of -1.5 m/s^2.the driver then applies brakes, causing a uniform acceleration of -2.1m/s^2 for an interval of 3.0s How far has it gone from its start?

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

0 = 0.40 / 0 = 0

= 0.20 = 9.80 ⁄2 =?

=0 , = = 0.20 =0.50 0 0.40 ⁄

=0−122 =0−12(9.80 ⁄2)(0.50)2 =1.2
