A 4.5-m-long wooden board with a 24-kg mass is supported in two places. One support is directly under the center of the board, a
nd the other is at one end. What can be said about the forces exerted by the supports?
2 answers:
Answer:
The support at the middle of the board exerts an upward force that is equal to the weight of the board mg ( 24x9.81)N which is 235.44N.
The support at the other end exerts no force on the board since the board is already balanced by the middle support.

Answer:
v_avg = 2.9 cm/s
Explanation:
The average velocity of the object is the sum of the distance of all its trajectories divided the time:
x_all is the total distance traveled by the object. In this case you have that the object traveled in the first trajectory 165cm-15cm = 150cm, and in the second one, 165cm - 25cm = 140cm
Then, x_all = 150cm + 140cm = 290cm
The average velocity is, for t = 100s
hence, the average velocity of the object in the total trajectory traveled is 2.9 cm/s
