A uniform thin rod of length 0.6 m and mass 6.00 kg is suspended freely from one end. It is pulled to the side an angle 60 degrees and released. If friction can be ignored, what is the speed of its free end (in m/s), at the lowest point? (Could you please explain what equation I can use to find it at it's lowest point as well as a step by step formula on how to fingure out this equation. Thank you, no rush).
As shown in the figure below, a 2.25 kg block is released from rest on a ramp of height h. When the block is released, it slides without friction to the bottom of the ramp, and then continues across a surface that is frictionless except for a rough patch of width 15.0 cm that has a coefficient of kinetic friction ?k = 0.510. Find h (in m) such that the block's speed after crossing the rough patch is 3.60 m/s. (Enter a number.)?m
A glider is placed at the top of an air track that is tilted at an angle of 7.7º from the horizontal. If the glider is then let go (from rest), what is its speed at the instant it has glided 0.275 mm along the track?
A 5.60-kg block is set into motion up an inclined plane with an initial speed of v¡ = 7.60 m/s (see figure below). %3D The block comes to rest after traveling d = 3.00 m along the plane, which is inclined at an angle of 0 = 30.0° to the %3D horizontal. (a) For this motion, determine the change in the block's kinetic energy. We know an initial speed and a final speed. Are the other pieces of information relevant to this question? J (b) For this motion, determine the change in potential energy of the block-Earth system. 82.3 J (c) Determine the friction force exerted on the block (assumed to be constant). You appear to have correctly calculated the force using your incorrect results from parts (a) and (b). N (d) What is the coefficient of kinetic friction? You appear to have calculated the coefficient correctly using your incorrect result from part (c).
The pulley system below consists of two masses connected by a string of negligible mass through a massless pulley. A spring with constant k is placed so that its equilibrium position is located a distance h below the bottom of mass m2. There is no friction either in the pulley, or between the surfaces of the masses and the platform. When the two masses m₁ and m2 are released from rest, mass m2 begins falling and pulls mass m₁ up the ramp. Find an expression for the maximum compression of the spring d caused by mass m2 when it hits the spring. Your answer should be in terms of the variables given (and g). m2 MW my 0

A miniature hill in a child’s toy collection is shown below. When released at A, a mass m slides down the path shown below, reaching the bottom (B) with a speed of vB. Assume that the hill has negligible friction. The block then slides along the rough horizontal surface a distance d before coming to rest at C. When solving parts (a) and (b): Write the useful description about what is known and unknown. Write down the physics principle or strategy you will use. Symbolically solve for the unknowns (a) Calculate the height of the hill using m=230.0 g and vB = 3.8 m/s (b) What is the coefficient of kinetic friction along the horizontal surface if d=14 m? Hint: Treat the motion down the hill and the motion down the rough horizontal surface as two distinct problems. What physics concepts can you apply for each?
