A race car is slowed with a constant acceleration of 11 m/s2 opposite the direction of motion. a. If the car is going 55 m/s, how many meters will it travel before it stops? m b. How many meters will it take to stop a car going twice as fast? m; this is times farther than stopping a car going half the speed.

What is the name for the remnant of an asymptotic giant that has lost its shells? black dwarf white dwarf yellow giant black hole

What can you increase the strength of an electromagnet by

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
