In the diagram above block A has a mass of 3.2 kg and block B a mass of 2.4 kg. The pulley is frictionless and has no mass.
The diagram above shows a marble rolling down an incline, the bottom part of which has been bent into a loop. The marble is released from point A at a height of 0.80 m above the ground. Point B is the lowest point and point C the highest point of the loop. The diameter of the loop is 0.35 m. The mass of the marble is 0.050 kg. Friction forces and any gain in kinetic energy due to the rotating of the marble can be ignored. When answering the following questions, consider the marble when it is at point C.
A planet of constant mass orbits the sun in an elliptical orbit. Neglecting any friction effects, what happens to the planet’s rotational kinetic energy about the sun’s center?
A gun can fire a bullet to height \( h \) when fired straight up. If the same gun is pointed at an angle of \( 45^\circ \) from the vertical, what is the new maximum height of the projectile?
A meter stick of mass [katex] .2 [/katex] kg is pivoted at one end and supported horizontally. A force of [katex] 3 [/katex] N downwards is applied to the free end, perpendicular to the length of the meter stick. What is the net torque about the pivot point?
A block is projected up a ramp with an initial speed \( v_0 \). It travels along the surface of the ramp with constant acceleration \( a \). Take the positive direction of motion to be up the ramp. If the acceleration vector points opposite the initial velocity vector, which of the following MUST be true?
An object is experiencing a nonzero net force. Which of the following statements is most accurate?
When is the angular momentum of a system constant?
A satellite in circular orbit around the Earth moves at constant speed. This orbit is maintained by the force of gravity between the Earth and the satellite, yet no work is done on the satellite. How is this possible?
A rock is whirled on the end of a string in a horizontal circle of radius R with a constant period T. If the radius of the circle is reduced to R/3, while the period remains T, what happens to the centripetal acceleration (ac) of the rock?
The magnitude of the gravitational field on the surface of a new planet is 20 N/kg. The planet’s mass half the mass of Earth. The radius of Earth is 6400 km. What is the radius of the new planet?
