Now watch the sequence 7:50 to 7:56 which shows an acrobat taking a long run down the trampoline, bouncing extremely high into the air several times, but then coming to a full stop on the trampoline. Consider two cases: (A) where the woman falls down from a great height onto the trampoline and rebounds back up to a great height, and (B) where the woman falls down from a great height, and comes to a full stop. For which case is the change in the woman's momentum the largest? For which case is the Impulse the largest?
The change in the momentum is largest for (A) and the impulse is the largest for (B).
The change in the momentum is largest for (B) and the impulse is the largest for (A).
The change in the momentum and the impulse is the largest for (A).
The change in the momentum and the impulse is the largest for (B).
A 9.00 kg point mass and a 15.0 kg point mass are held in place 50.0 cm apart. A particle of mass m is released from a point between the two masses 19.0 cm from the 9.00 kg mass along the line connecting the two fixed masses.
IP Halley's Comet Halley's Comet, which passes around the Sun every 78 years, has an elliptical orbit. When closest to the Sun (perihelion) it is at a distance of 8.823 x 10^10 m and moves with a speed of 54.6 km/s. The greatest distance between Hall..
