Forces-And-Newton-s-Laws Questions
An object with a mass of # 12 kg# is lying still on a surface and is compressing a horizontal spring by #1 m#. If the spring's constant is # 2 (kg)/s^2#, what is the minimum value of the surface's coefficient of static friction?
How fast will an object with a mass of #15 kg# accelerate if a force of # 75 N# is constantly applied to it?
An object with a mass of #4 kg# is pushed along a linear path with a kinetic friction coefficient of #u_k(x)= 5+tanx #. How much work would it take to move the object over #x in [(pi)/12, (pi)/4]#, where x is in meters?
How fast will an object with a mass of #8kg# accelerate if a force of #20 N# is constantly applied to it?
An object with a mass of #4 kg# is acted on by two forces. The first is #F_1= < 6 N , -2 N># and the second is #F_2 = < -5 N, 3 N>#. What is the object's rate and direction of acceleration?
How is the average force of friction calculated?
An object with a mass of #4 kg# is acted on by two forces. The first is #F_1= < -5 N , 2 N># and the second is #F_2 = < -2 N, 3 N>#. What is the object's rate and direction of acceleration?
Car is driving with a speed of 36km/h. Then the car stops completely in 2 seconds. What is the negative acceleration of the car?
A remote control car has a mass of #15.5kg# and is accelerating on the road. The car starts from rest and reaches a velocity of #11m/s[E]# in #19.5s#. What is the force applied by the car on the road? Neglect frictional forces.
How fast will an object with a mass of #24 kg# accelerate if a force # 45 N# is constantly applied to it?
How fast will an object with a mass of #16 kg# accelerate if a force of #32 N# is constantly applied to it?
An object with a mass of #6 kg# is pushed along a linear path with a kinetic friction coefficient of #u_k(x)= 2+cscx #. How much work would it take to move the object over #x in [pi/8, (3pi)/8], where x is in meters?
