ohn and Jack are planning to do a physics lab related to vectors. Starting at the door of their physics classroom, they walk 2.0 meters, south. They make a right hand turn and walk 16.0 meters, west. They turn right again and walk 24.0 meters, north. They...

Calculate the net or resultant force in N in x direction given that F1=96.2 N is applied at angle of α=55.4° and a second F2=11.6 N is applied at angle of β=41.2°. See attached figure. Express your answer to 4 significant figures.

Sled accelerates at 2m/s^2. If net force is tripled and mass is doubled then what is the new acceleration of the sled?

Calculate the relative concentration of phenol (ka=1.05x10^10) and phenolate ion in a solution with 0.05M total phenol (pH=7.5)

Thank you!!

Ms. Sue, you didn't even help the poor guy (or girl?). To compare, you have to find the range between the two. The range is 6 years.
