h 5. A cart rolls with negligible friction down a ramp that is inclined at an 8 = 32' above level ground. It is released from rest at a height h = 52 cm. What we want to do is to figure out how fast the cart will go when it reaches the bottom of the ramp. Let's begin by establishing the equations that model the motion of the cart. Recall that we are dealing here with an example of...

1) A solid ball of mass M and radius R rolls without slipping down a hill with slope tan θ. (That is θ is the angle of the hill relative to the horizontal direction.) What is the static frictional force acting on it? It is possible to solve this question in a fairly simple way using two ingredients: a) As derived in the worksheet when an object of moment of inertia I, mass M and radius R starts at rest...

Problem 1 A roller coaster cart has a mass of 200.0kg, which includes its passengers. The cart is pushed off its beginning position by a spring with a spring constant of k 150.ON/m that has been compressed by Ax 0.50m from its equilibrium length. Friction is negligible everywhere, except for a 2-meter-long rough patch on the initial slide (see the figure below), where the coefficient of kinetic friction is uk 0.4. (For the purposes of calculation involving friction, here you...

A cart of mass m rolls without friction on a level
surface, and is attached to a light spring of constant k,
the other end of which is attached to a wall. Take the initial
position of the cart, where the spring is neither extended nor
compressed, to be the origin x = 0 of a coordinate system
where positive x values are to the right and positive
vectors point to the right. The cart is pushed to the left...

A mass M slides downward along a rough plane surface inclined at angle \Theta\: Θ = 29.8 in degrees relative to the horizontal. Initially the mass has a speed V_0\: V 0 = 5.32 m/s, before it slides a distance L = 1.0 m down the incline. During this sliding, the magnitude of the power associated with the work done by friction is equal to the magnitude of the power associated with the work done by the gravitational force. What...

A mass M slides downward along a rough plane surface inclined at angle \Theta\: Θ = 31.7 in degrees relative to the horizontal. Initially the mass has a speed V_0\: V 0 = 6.9 m/s, before it slides a distance L = 1.0 m down the incline. During this sliding, the magnitude of the power associated with the work done by friction is equal to the magnitude of the power associated with the work done by the gravitational force. What...
