Three sleds of masses mı, m2, and m3 are on a smooth surface (ice) inclined at an angle relative to the horizontal and
connected by ropes as shown in (Figure 1). Imagine that you
exert force of a known magnitude T on the rope attached to the
first sled.
determine the magnitude of the tension in the rope that connects sled one (mass M1) and sled two (mass M2). determine the magnitude of the tension in the rope that connects sled 2 (mass m2) and sled 3 (mass m3)

Choose the most likely outcome of this scenario: jen decided to go bike riding without a helmet. while no one is around during her ride, she is thrown from her bike when her wheel goes into a pothole. she is not injured, but she is terrified to get back on her bike. what happens next? a. her physical health is affected even though she wasn't hurt. b. her mental and emotional health are affected because she is afraid to get back on her bike. c. her social health is affected because she is worried her friends saw the fall. d. her overall health is not affected at all by her fall.

In science and physics what is the standard unit of measure for speed?

Amoving electron has kinetic energy k1. after a net amount of work w has been done on it, the electron is moving one-quarter as fast in the opposite direction. (a) find w in terms of k1. (b) does your answer depend on the final direction of the electron's motion?
