I posted this question earlier and I still don't get it So I got a question One 3.5-kg paint bucket is hanging by a massless cord from another 3.5-kg pain bucket, aslo hanging by a massless cord if the buckets are at rest, what is the tension in each cord? How do I do this...

So I got a question One 3.5-kg paint bucket is hanging by a massless cord from another 3.5-kg pain bucket, aslo hanging by a massless cord if the buckets are at rest, what is the tension in each cord? How do I do this is this just the normal or what I do not understand how you...

ok thanks

ok so I have a question At the instatn a race began, a 57-kg sprinter was found to exert a force of 80 N on the starting lbock at 22 degrees with respect to the ground what was the horizontal acceleration of the sprinter? I got roughly 1.3 s^-2 m ok here's were i need some...

ok uh I still don't completly understand I thought I was trying to get it to point westward not south west also what about the basketball player question

Physics
I have two questions this one A 750-N force acts in a northweserly direction. A secon 750-N force must be exerted in what direction so that the resultant of the two forces points westward? I have no idea how to go about solving this prolbem second Draw the free body diagram fo...

When I asked my teacher for help he told me this This is a logical puzzle. Having 75% of the typical weight means experiencing 75% of the typical gravity. The floor must be falling away with an acceleration of 25% of typical gravity. Here's the question I asked that's ...

My question is A block is given an intial speed of 4.0 s^-1 m up the 22 degree plane How far up the plane will it go? How much time elapses before it returns to its starting point? Ignore friction. Ok my teacher said use this to find acceleration a = g sin è and then I ...

what is newtons method isn't the formula suppose to be y = Vo t - 2^-1 g t^2 ????? -1.5 = u sin(10) -(1/2)g t2 instead of that shouldn't it be -1.5 = (u sin(10))? -(1/2)g t2

Ok the problem I'm doing has two parts I know how to do part a and got the right answer I think... I do not know how to do part b Here's the problem A student driver wants to make his car jump over 8 cars parked side by side below a horizontal ramp (a)With what minimum...
