An eletron moves with a constant horizontal velocity of 3.0*10^6 m/s and no intial vertical velocity as it enters a deflector inside the TV tube. The electron strikes the screen after traveling 17 cm horizontally and 40 cm vertically upward with no horizontal acceleration. What is the constant vertical accelerartion provided by the deflector?

A space shuttle is in a circular orbit at a height H above the Earth. A small satellite is held above the shuttle (i.e. directly away from the Earth) by means of a rod of length h and then released. What is its initial motion relative to the shuttle?
A package of mass 7 kg sits at the equator of an airless asteroid of mass 4.0 1020 kg and radius 5.9 105 m. We want to launch the package in such a way that it will never come back, and when it is very far from the asteroid it will be traveling with speed 188 m/s. We have a large and powerful spring whose stiffness is 2.1 105 N/m. How much must we compress the spring?
A carriage runs along rails on a rigid beam. The carriage is attached to one end of a spring of equilibrium length r0 and force constant k, whose other end is fixed on the beam. On the carriage, another set of rails is perpendicular to the first along which a particle of mass m moves, held by a spring fixed on the beam, of force constant k and zero equilibrium length. Beam, rails, springs, and carriage are assumed to have zero mass. The whole system is forced to move in a plane about the point of attachment of the first spring, with a constant angular speed ω. The length of the second spring is at all times considered small compared to r0. What is the energy of the system? Is it conserved?

A record is played by spinning the record so that a circular groove in the vinyl slides under the stylus. Suppose that a record turns at a rate of 33 1/3 rev. min, the groove being played is at a radius of 10.0 cm and the bumps in the grove are uniformly separated by 1.75 mm. At what rate (hits per second) do the bumps hit the stylus? Enter units as hertz (Hz). You will need v=rω ω is in rad/s and 1rev = 2 pi rad.
An object of mass m₁ = 4.00 kg is tied to an object of mass m₂ = 3.00 kg with String 1 of length 1 = 0.500 m. The combination is swung in a vertical circle on a second string, String 2, of length 1 = 0.500 m. During the motion, the two strings remain in line with one another as shown. At the top of its motion, m₂ is traveling at v = 4.00 m/s. a. Draw the force diagrams for both objects when at the top of the swing. 1 mi String 1 mo String 2 b. Given that m2 is traveling at v₂ = 4.00 m/s at the top, what must be the velocity of m₁ at this point? You should be able to reason it out.
A rod of mass M and length L is attached to a wall with a pin joint, around which the rod is free to rotate. A horizontal rope attached to the end of the rod holds the rod at an angle θo to the horizontal. Express your answer in terms of M, L, θo, and g (and no other variables). What is the tension in the rope? Suddenly the rope breaks. As a result, the rod swings down. Immediately after the rope breaks, what is the rod’s angular acceleration?

A 200 kg mass hangs from a 300 m cable on Mars (g=3.71 m/s2). It is displaced left from equilibrium along an arc with length 30 m and released at t = 0. What is its position relative to equilibrium when t = 20 s? What is its acceleration?
A 50-lb sphere A with a radius of 4.5 in. is moving with a velocity of magnitude v0 = 6 ft/s. Sphere A strikes a 4.6-lb sphere B that has a radius of 2 in., is hanging from an inextensible cord, and is initially at rest. Knowing that sphere B swings to a maximum height of h= 0.75 ft, determine the coefficient of restitution between the two spheres.
A long limp spring is hung from a beam; the spring's bottom is 660 mm above the table. A 0.50 kg cylinder is hooked to the spring's bottom while the spring hangs relaxed. When the cylinder is dropped, it turns around just above the table, where the spring's bottom had been stretched to 10 mm above the table. What is the cylinder's velocity, half-way to the bottom turn-around?
