An aircraft with a mass of 956 kg accelerates from 0 to 92 m/s in 6.7 seconds, at which time the aircraft launches.
Light from a helium-neon laser (wavelength=633 nm) is focused through a pinhole prior to illuminating a 1.00 mm diameter aperture. If the pinhole is located 50.0 cm behind the diffracting aperture, how far in front of the aperture should an observ..
A person who is properly restrained by an over-the-shoulder seatbelt has a good chance of surviving a car collision if the deceleration does not exceed 30 "g's"(1.00g = 9.80 m/s2).
The 1.1 kg balls are attached to the ends of a thin rod of length 42.0 cm and negligible mass. The rod is free to rotate in avertical plane without friction about a horizontal axis through its center.
A nylon guitar string has a linear density of 7.0 g/m and is under a tension of 155 N. The fixed supports are distance D = 90.0 cm apart. The string is oscillating in the standing wave pattern shown in Figure 16-39
what is the saturation activity of 24na that can be induced in a 400 g sample of nacl with a constant thermal-neutron
A 2.0 kg mass traveling at 3.0 m/s strikes another 2.0 kg mass traveling at -1.0 m/s. They collide and have a complete elastic collision. what does the first mass do
Preparing to throw baton A in the air, you hold it at the midpoint and give it a twist with your forearm and wrist that applies a torque of 1.4 m·N for a time interval of 0.50 s. What would be the moment of inertia
You ski straight down a 43.4° slope, starting from rest and traveling a distance of 10.3 m along the slope. Find your final velocity
Consider a giant funnel that slopes at an angle of theta. the bottom has an area (a) equal to 3.0 x 10-4 m. Determine how long it takes for half of the water to drain
A 1.2 kg block is held at rest against a spring with a forceconstant k=730 N/m. Intially the spring is compressed a distanced. When the block is released, it slides across a surfacethat is frictionless except for a rough patch of width 5.0 cm that..
One particle, of mass m, moves with a speed v in the x-direction, and another particle, of mass 2m, moves with a speed v/2 in the y-direction. What is the velocity of the center of mass of these two particles
A skier starts at rest at the top of a large hemispherical hill with radius (height) = R. Neglecting friction, show that the skier will leave the hill and become airborne at the distance of h = R/3below the top of the hill.
