You are hungry and decide to go to your favorite neighborhood fast-food restaurant. You leave your apartment and take the elevator 10 flights down (each flight is 3.0m) and then go 15msouth to the apartment exit. You then proceed 0.2kmeast, turn north, and go 0.1kmto the entrance of the restaurant.
Determine the displacement from your apartment to the restaurant. Use unit vector notation for your answer, being sure to make clear your choice of coordinates.
Take the beginning of the journey as the origin, with north being the y-direction, east the x-direction, and the z-axis vertical.
A 1130 kg car traveling initially with a speed of 25.60 m/s in an easterly direction crashes into the back of a 9 550 kg truck moving in the same direction at 20.0 m/s. What was the velocity of the truck right after the collision
the eye of a hurricane passes over grand bahama island in a direction 60.0deg north of west with a speed of 38.0 kmh.
An aluminum container which has a mass of 0.350 kg holds 0.70 kg of water. The water and container are both at 45.0°C. How much ice is required
A tightrope walker is practicing. She is balanced on a rope at the exact midpoint of the rope. The tension in the rope is 4000 N, and the mass of the tightrope walker is 56 kg. Consider the left side of the rope. What angle with the horizontal does i..
A pendulum consists of a 320-{\rm g} solid ball15.0 {\rm cm} in diameter, suspended with an essentially mass less string 60.0 {\rm cm} long. Compute the period of this pendulum, treating as a simple pendulum.
A sphere of radius 1.0 cm is dropped into a glass cylinder filledwith a viscous liquid. What is the viscosity of the liquid
What is the minimum thickness of coating which should be placed on a lens in order to minimize reflection of 406 nm light? The index of refraction of the coating material is 1.54 and the index of the glass is 1.79.
A +1 uC charge is held 10 cm directly above the origin. A -1 uC charge is held 5 cm directly to the right of the origin. What is the electric potential at the origin
An electron (m = 9.109 x 10-31kg) is in the presence of a constant electric field E. The electron has a charge of e = 1.602 x 10-19 C and it accelerates at a rate of a = 7800 m/s2. Write an expression for the magnitude of the electric field.
