The Earth has an angular speed of 7.272·10-5 rad/s in its rotation.Find the new angular speed if an asteroid (m = 4.99·1022 kg) hits the Earth while traveling at a speed of 2.19·103 m/s (assume the asteroid is a point mass compared to the radius of the Earth) in each of the following cases:
a) The asteroid hits the Earth dead center
b) The asteroid hits the Earth nearly tangentially in the direction of Earth's rotation
c) The asteroid hits the Earth nearly tangentially in the direction opposite of Earth's rotation.
A student, starting from rest, slides down a water slide. On the way down, a kinetic frictional force (a nonconservative force) acts on her. how fast is the student going at the bottom of the slide
The 150-lb man lies against lies against the cushion for which the coefficient of static friction is 0.5. Determine the resultant normal and frictional forces the cushion exerts on him if, due to rotation about the z axis, he has a constant speed v =..
One way to decrease your use of fossil fuels is to heat your water via solar radiation. A solar water heater runs cold water through dark, radiation absorbing tubing.
