The concepts in this problem are similar to those in Multiple-Concept Example 4, except that the force doing the work in this problem is the tension in the cable. A rescue helicopter lifts a 83.3-kg person straight up by means of a cable. The person has an upward acceleration of 0.777 m/s2 and is lifted from rest through a distance of 8.54 m. (a) What is the tension in the cable

In what direction does the medium move relative to the direction of the wave? explain.

Aball tossed vertically upward from the ground next to a building passes the bottom of a window 1.8 s after being tossed and passes the top of the window 0.20 s later. the window is 2.0 m high from top to bottom. what was the ball's initial velocity? the unit vector j^ is directed upward. how far is the bottom of the window from the launch position? how high does the ball rise above the launch position?

According to newton’s first law of motion, which force is expected to cause a body to accelerate?
