A painter with 80 weight is on a 4 meters long platform. Platform has negligible weight. The painter is balanced by two cables. One is at the left end and the other one is 3.2 meters away from the first cable. a)What is the tension on the left cable and the right cable when the painter is in the middle of the platform b)Would the painter be able to move the right end of the platform without loosing balance. Calculate the tensions on the cables for that case and show that it leads to a negative tension.

A man standing on the ground exerts a horizontal force of 439 N when pushing on his friend standing on the skateboard.If the friend’s mass is 70 kg, the skateboard’s mass is 2 kg, and the coefficient of static friction between the friend’sfeet and the skateboard is 0.8, calculate the magnitude of the force of static friction between the skateboard and thefriend’s feet. You can assume that the wheels on the skateboard are good enough so that you can neglect frictionbetween the wheels and the ground.
The answer should be in 3 significant digits
