An object with a mass of #2 kg# is on a plane with an incline of #pi/8 #. If the object is being pushed up the plane with # 8 N # of force, what is the net force on the object?

An object with a mass of #4 kg# is acted on by two forces. The first is #F_1= < -3 N , 6 N># and the second is #F_2 = < 7 N, -8 N>#. What is the object's rate and direction of acceleration?

What is the weight in lbs of a 75-kg person?

What was Heisenberg's contribution to the atomic model?

An object with a mass of #12 kg# is on a plane with an incline of # -(3 pi)/8 #. If it takes #25 N# to start pushing the object down the plane and #15 N# to keep pushing it, what are the coefficients of static and kinetic friction?

The gas inside of a container exerts #15 Pa# of pressure and is at a temperature of #50 ^o K#. If the temperature of the gas changes to #90 ^oK# with no change in the container's volume, what is the new pressure of the gas?
