A skateboarder shoots off a ramp with a velocity of 6.6m/s directed at an angle of 58 degrees above the horizontal. The end of the ramp is 1.2m above the ground. Let the x axis be parallel to the ground,+y direction be vertically upward, and take as the origin the point on the ground directly below the top of the ramp. (a) How high above the ground is the highest point that the skateboader reaches? (b) When the skateboarder reaches the highest point, how far is this point horizontally from the end of the ramp?
A simple pendulum is made of a small blob of mass m = 7.000 kg attached to the end of an inextensible wire. The angular amplitude of oscillation is ?0 = 7.162°. What is the magnitude of the tension in the wire when the blob is directly below its poin..
A microscope uses beams of protons instead of photons/electrons. What wavelength would the beam of protons have if their momentum was acquired from a potential drop of 100 volts? (The answer is 2.87*10^-10 cm, but I don't know how to get there
A particle is executing simple harmonic motion with an agular frequency w=27.8Hz. What are respectively the period and frequency of this vibration?
Electrons are accelerated from rest through a potential difference of 350V and then enter a uniform magnetic field that is perpendicular to the velocity of the electrons. what is the angular speed of this electron
A 9.59-g bullet, moving horizontally with an initial speed v0, embeds itself in a 1.45-kg pendulum bob that is initially at rest. Find the initial speed of the bullet.
