**A mass m2 = 1.5 kg is initially moving with velocity vo. It collides completely inelastically with a block of mass m2 = 2.0 kg. The second block is attached to a spring with a spring constant of k = 5.6x10ʻN/m. The
block and spring lie on a frictionless horizontal surface. The spring compresses a distance of 0.20 m upon
collision
(a) What is the velocity of the mass mi and the block immediately after the collision?
(b) What is the initial velocity of the mass mi immediately before the collision?
(C) If the block were attached to a long string and hung as a pendulum, how high would the block and mass
mi rise after the collision?

We all use gps today, even if we don't drive yet. i bet you have been in the car with a parent and they have asked you to get out your phone to find a specific location. in your car, on the phone, you are using a very sophisticated technology. gps satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. gps receivers take this information and use trilateration to calculate the user's exact location. essentially, the gps receiver compares the time a signal was transmitted by a satellite with the time it was received. the time difference tells the gps receiver how far away the satellite is. now, with distance measurements from a few more satellites, the receiver can determine the user's position and display it on the unit's electronic map. what type of signal is utilized by the gps satellite?

Aforce of 200 n is applied to an input piston of cross-sectional area 2 sq. cm pushing it downward 2.8 cm. how far does the output piston of cross-sectional area 12 sq. cm move upward? show all work.

The star betelgeuse is about 600 light-years away. if it explodes tonight, a. we'll know because debris from the explosion will rain down on us from space. b. we'll know it immediately because it will be brighter than the full moon in the sky. c. we won't know about it until 600 years from now. d. none of the above.
