friction is the resistance that one surface or object encounters when moving over another. Due to gravity pulling everything down things need to friction in order to move
i hope this helps :/
Answer:
i assume the system is in equilibrium
Explanation:
(W_p-T)(2)+W_b(2.5)= T(sin 45 degrees)(5)
T(((sin 45 degrees)(5)) + 2) = (W_p)(2) + W_b(2.5)= T(5.5355)
Answer:
80 times 12=960
Explanation:
You have to do the equation for work, the equation is work= force times distance, the force here is 80newtons, the distance is 12meters, so you would do 80 times 12 to get your answer of 960
