I did not post any formulas because I am not sure what I can use. Like this question doesent use any numbers, you are only supplied with generalizations of certain aspects. Like friction is negligaable. Also since the cart is at a height you can use potential energy formula. But I still can't...

Hi I am working on an assignment and I honeslty am completely baffled with this question. I have no idea how to go about trying to figure it out as its purely conceptual based. If anyone has any info that might help, I am all ears. The problem is as follows and I am attaching the diagram as...

Hi i tried this problem a couple times but could not figure out...thought maybe i could get some help 1. Homework Statement [/b] A 10 000 -kg bridge of length 10 m is supported at both ends. If a 2000-kg car is parked on the bridge 3.0 m from the left support, what are the supporting...

im not sure what that means...could you please explain what u just posted

Hi, I did this question one way and realized my answer was totally wrong. Was wondering if anyone knew a possible solution for this problem. 1. The leg is in the cast in the diagram shown below weight 220N(w1). The leg is held in traction by two weights (w2 and w3) attached to stings and...

thanks so much for the help i really appreciate it

ok so then this is what i think the solution would be Fnet = 400 - mg a= Fnet / m a= (400 - (25)(9.8))/25 and that should give me the answer i need. That does that seem right to u?

is it 400 N? so Fnet = 400 - mg?

I am not sure how to find the net force. Am i right in asuming that the 2 forces acting on the object, is the downward force of m*g and the upwards force of m*-g?

i can't figure out net force as i do not have acceleration...all i have is what is the max load the rope can take which is 400, the gravity which is -9.8 as it is going upwards and the 25 kg load

Hi I tried this question a couple times, couldn't figure it out, thought maybe you guys could help. 1. The maximum load that can safely be supported by a rope in an overhead hoist is 400N. What is the maximum acceleration that can safely be given to a 25kg object being hoisted vertically...
