In Anchorage, collisions of a vehicle with a moose are so common that they are referred to with the abbreviation MVC. Suppose a 950 kg car slides into a stationary 400 kg moose on a very slippery road, with the moose being thrown through the windshield (a common MVC result).
(a) What percent of the original kinetic energy is lost in the collision to other forms of energy? A similar danger occurs in Saudi Arabia because of camel-vehicle collisions (CVC).
(b) What percent of the original kinetic energy is lost if the car hits a 320 kg camel?
(c) Generally, does the percent loss increase (if so type 1) or decrease (if so type 2) if the animal mass decreases?
A potential difference of ?V = 12.0 V is found to produce a current of 0.40 A in a 3.2 m length of wire with a uniform radius of 0.40 cm, What is the resistivity of the wire
A flight attendant pulls her 70 N flight bag a distance of 247 m along a level airport floor at a constant speed. The force she exerts is 33.00 N at an angle of 52° above the horizontal.
A 75 , 33 long rod hangs vertically on a frictionless, horizontal axle passing by its center. A 12 ball of clay traveling horizontally at 2.6 hits and sticks to the very bottom tip of the rod.
Calculate the value of the error (only) with two decimal places for: (5.3 +/- 0.1) / (2.9 +/- 0.1) and (7.3 +/- 0.4) / (3 +/- 0.2)
find the energy in joules of the photons.
What is tension in each rope
Sketch a force diagram for the desk.
Just after each jumps, that person is moving away from the crate with a speed of 4.40 m/s relative to the crate.
Two automobiles drive in the same direction next to the highway. Each moves initially at speed v = 30 meters per second, (that's 67.11 miles per hour) and the distance between them is D meters.
An 8-kg ball hanging from the ceiling by a light wire 135cm long is struck in an elastic collision by a 2 kg ball moving horizontally at 5.00 m/s just before the collision. Find the tension in the wire just after collision.
1. A modern-day zeppelin holds 8,280 m3 of helium, Compute its maximum payload at sea level
Jupiter is 23.10 m/s2. What is the ratio of your speed on Jupiter to your speed on Earth when you have dropped 45.0 m? Overlook the effects of air resistance and suppose that you start at rest.
