A bullet with mass m and speed v is fired at a ballistic pendulum bob of mass M. The bob is attached to a thin, light rod of length L, hangs vertically initially, and is attached to a pivot at its top end. A) Find v so that the rod swings up and is horizontal at the max height of the bob. B) Find the minimum v so that the rod will make a complete circle C) Find v so that the tension in the rod is zero at the top of its swing.
A proton is initially at rest at a point where the potential is 515V. Sometime later the proton is at a point where the potential is 190V. If no force other than the electrostatic force acts on the proton, what is its final kinetic energy.
A flywheel in a motor is spinning at 560 when a power failure suddenly occurs. The flywheel has mass 40.0 and diameter 75.0. The power is off for 34.0, and during this time the flywheel slows down uniformly due to friction in its axle bearings. Durin..
Batteries are rated in terms of ampere-hours (A h). For example, a battery that can produce the current of 3.00 A for 5.00 h is rated at 15.00 A h. What is the total energy stored in an 8.0-V battery rated at 49.0 A h.
A hockey puck is sliding across a frozen pond with an initial speed of 9.7 ms. It comes to rest after sliding a distance of 44.0 m. What is the coefficient of kinetic friction between puck and ice.
A toy car moves at a velocity of 65.00 m/s on a compass heading of 115degrees. What are the components, magnitude and direction of car.
A helicopter is rising at 4.60 m/s when a bag of its cargo is dropped. The bag falls for 2.50 s. (suppose that the positive direction is upward.)
Once can set up a two-dimensional scattering theory that could be applied to puck projectiles sliding on an ice rink and colliding with various target obstacles.
At t = 0 a grinding wheel has an angular velocity of 27.0 rad/s. It has a constant angular acceleration of 32.0 rad/s2 until a circuit breaker trips at t = 2s. From then on, it turns by 432 rad as it coasts to a stop at constant angular accelerati..
A 5.40×10-2- wad of putty is thrown horizontally at the block, hitting it with a speed of 2 and sticking. far does the putty-block system compress spring.
A spring (k =805N/m) is hanging from ceiling of an elevator, and a 5.0-kg object is attached to the lower end. By how much does the spring stretch (relative to its unstrained length) when the elevator is accelerating upward at a = 0.47m/s2.
Using the kinematic equation, prove that if two balls are released simultaneously from table, one with zero velocity and the other with a horizontal velocity, they would both reach the ground at the identical time.
A thin, flexible metal plate attached at one end to the platform, can be used to measure mass. When the free end of the plate is pulled down and released, it vibrates in simple harmonic motion with a period that depends on the mass attached to the pl..
