Forces-And-Newton-s-Laws Questions
A box with a mass of #4 kg # and initial speed of #3 m/s# is moving up a ramp. The ramp has a kinetic friction coefficient of #2 # and an incline of #pi /12 #. How far along the ramp will the box go?
A box with an initial speed of #3 m/s# is moving up a ramp. The ramp has a kinetic friction coefficient of #8/7 # and an incline of #( pi )/4 #. How far along the ramp will the box go?
An object with a mass of #8 kg# is acted on by two forces. The first is #F_1= < -9 N , 2 N># and the second is #F_2 = < -4 N, -3 N>#. What is the object's magnitude and direction of acceleration?
How fast will an object with a mass of #15 kg# accelerate if a force of #35 N# is constantly applied to it?
A box with an initial speed of #3 m/s# is moving up a ramp. The ramp has a kinetic friction coefficient of #2/5 # and an incline of #( pi )/8 #. How far along the ramp will the box go?
An object with a mass of #8 kg# is acted on by two forces. The first is #F_1= < -2 N , 1 N># and the second is #F_2 = < 3 N, -1 N>#. What is the object's rate and direction of acceleration?
An object, previously at rest, slides #5 m# down a ramp, with an incline of #pi/6 #, and then slides horizontally on the floor for another #1 m#. If the ramp and floor are made of the same material, what is the material's kinetic friction coefficient?
What are action and reaction pairs?
An object with a mass of #4 kg# is lying still on a surface and is compressing a horizontal spring by #1/4 m#. If the spring's constant is #3 (kg)/s^2#, what is the minimum value of the surface's coefficient of static friction?
If the length of a #32 cm# spring increases to #71 cm# when a #4 kg# weight is hanging from it, what is the spring's constant?
An object with a mass of # 5 kg# is lying on a surface and is compressing a horizontal spring by #20 cm#. If the spring's constant is # 9 (kg)/s^2#, what is the minimum value of the surface's coefficient of static friction?
If the length of a #37 cm# spring increases to #77 cm# when a #3 kg# weight is hanging from it, what is the spring's constant?
