Q1. A 13g bullet travelling 233 m/s penetrates the 2.0kg block of wood and emerges going 175 m/s. If the block is stationary on the frictionless surface when hit, how fast does it move after the bullet emerges?
Q2. Therefore of his observations, Ole Roemer concluded that eclipses of Io by Jupiter were delayed by 22 min throughout a six-month period as the Earth moved from the point in its orbit where it is closest to Jupiter to the diametrically opposite point where it is farthest from Jupiter. Using the value 1.50 x 10^8 km as the average radius of the Earth's orbit around Sun, calculate the speed of light from these data.
Compute the force of tension or compression
A super tanker with the mass of 3.36 × 109 kg is moving with a constant velocity. Its engines generate a forward thrust of 4.11 × 105 N. Determine (a) magnitude of the resistive force exerted on the tanker by the water and (b) magnitude of the upward..
An ocean liner leaves New York City and travels 37.0° north of east for 171 km. How far east and how far north has it disappeared? In other words, what are the magnitudes of the components of the ship's displacement vector in the directions.
What is wave speed
A 362 g object is attached to a spring and executes simple harmonic motion with the period of 0.200 s. If the total energy of the system is 6.71 J.
Sea Launch mission planners are going to launch their Russian launch vehicle from a Lo = 3 degrees into LEO with an inclination of 34 degrees and the longitude of ascending node of 124 degrees. Current LST at the launch site is 1140.
A force vector points at an angle of 50.6° above the +x axis. It has a y component of +280 newtons. Calculate the magnitude of the force vector.
How to find the magnetic field
What type of car was involved in the hit and run
A 346-, uniform, 1.04- bar is suspended horizontally by two vertical cables at each end. Cable A can support a maximum tension of 506.0 without breaking, and cable B can support up to 436.0. You want to place a small weight on this bar. What is the h..
A jetliner can fly 5.32 hours on a full load of fuel. Without any wind it flies at the speed of 220 m/s. The plane is to make a round-trip by heading due west for a certain distance, turning around, and then heading due east for the return trip.
A spring with spring constant 14 hangs from the ceiling. A ball is attached to the spring and allowed to come to rest. It is then pulled down 3.0 and released. The ball makes 17 oscillations in 16 seconds. What is it the mass of ball.
