Astring is attached to the rear-view mirror of a car. a ball is hanging on the other end of the
string. the car is driving along a circular path, at a constant speed. which of the following lists
gives all of the forces directly acting on the ball?
a. tension
b. tension and gravity
c. tension and centripetal force
d. tension, gravity and centripetal force
e. tension, gravity, centripetal force and friction

Atelevision set that has been running for a while heats up even the air around it. which two laws of thermodynamics could be used to analyze this scenario

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
