A race car starting from rest accelerates uniformly at a rate of 1.90 meters per second2. What is the car's speed after it
2.2 minutes

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.

answer a fan shaped mass of sediment deposited at the base of a mountain front do to an abrupt change in stream gradient;
