Q1. A person jumps from a fourth story window of a burning building.
They are 15.0 m above a fire-fighters safety net. When landing jumper stretches the net 1.0 m before coming to rest. A. what was the average acceleration experienced by the jumper when slowed to rest by the net? B. Is this acceleration positive or negative?
Q2. A strong lightning bolt transfers about 25C to Earth?
a) How many electrons are transferred?
b) If each water molecule donates one electron, what mass of water lost an electron to the lightning? One mole of water has the mass of 18 g.
A rifle with a barrel length of 62 cm fires a 12 g bullet with a horizontal speed of 460 m/s/s. The bullet strikes a block of wood and penetrates to a depth of 15 cm.
A helicopter is ascending perpendicularly with a speed of 5.42 m/s. At a height of 146 m above the Earth, a package is dropped from a window. How much time does it take for package to reach the ground.
The springs of a 1600 kg car compress 5.0 mm when its 65 kg driver gets into the driver's seat. If the car goes over a bump, what would be frequency of vibrations.
Compute the density of entropically raised element of air
Two spherical objects have a combined mass of 200. The gravitational attraction between them is 8.01×10-6 while their centers are 21.0 apart.
A gun is fired vertically into a 2.00 kg block of wood at rest straight above it. If the bullet has a mass of 21.0 g and a speed of 198 m/s, how high would the block rise into the air after the bullet becomes embedded in it.
Find out line linking the two point charges
Estimate approximately the angular deflection of the muon's trajectory, given that the rest mass of muon is 100Mev and that the saturation magnetization in iron is equivalent to 1.6 x 10^23 electron moments per cm^3.
A space vehicle is coasting at a constant velocity of 28.5 m/s in the +y direction relative to a space station. The pilot of the vehicle fires a RCS (reaction control system) thruster, which causes it to accelerate at 0.523 m/s2 in the +x direction.
