p7.png Two objects are connected by a rope over a massless, frictionless, pulley. The coefficient of kinetic friction  the surface and m2 is μ = 2.5  Assume m2 slides up the ramp, and determine the acceleration of the masses for m1 = 40.0 kg, m2 = 10.0 kg, and θ= 30.00

A mass m1 = 5.0 kg collides with a mass m2.  The mass m2 accelerates at 4.0 m/s2 and m1 decelerates at 6.0  m/s2.  What is the mass of  m2?

p13.png The coefficient of kinetic friction between the surface and m2 is μ = 0.30.  Determine the acceleration of the masses for m1 = 15.0 kg and m2 = 10.0 kg.

p11.png Determine the maximum angle the incline can be raised to without the crate sliding from rest if the coefficient of static friction between the surface and the crate is 0.65 and mass of the crate is 25 kg.

p7.png Two objects are connected by a rope over a massless, frictionless, pulley. Take the surface m2 sits on as frictionless and determine the acceleration of the objects for m1 = 10 kg, m2 = 15 kg, and q = 300 Take the acceleration as positive if m1 falls and negative if m1 rises.

At what angle would a circular track of radius 75 m need to be banked, so that a car traveling at 25 m/s around the track would not need friction to keep from sliding off?

What maximum speed can a car travel around a circular track of radius 150 m banked at 400 and not slide off, if the coefficient of static friction between the tires and the track is 0.7?

p7(1).png A roller coaster makes an inside vertical circle as shown.  If the circle has a radius of 50.0 m and the car is traveling at 25 m/s, determine the normal force on a rider of mass 75 kg in the car.
