A car is traveling at a constant initial velocity of 100km/h on a level portion of road. It encounters a 6 percent incline (tan(theta)= 6/100) at point A and the car decelerates at a constant rate of gsin(theta). Find the speed of the car (a) 10 seconds after passing point A a...

my dauter have a math problem and I dont no how to help her. this is the question: estimate each diffirence using compatible numbers for exc. 53-24=30 the next is 346-78=? we don`t now the answer thank you.Jessi

can someone please help me asap with this two problems I'm really stuck here. 1) solve for j if b=j+v/2 2) 9r+9s+9

physics
yeah the coefficient of static friction is 0.5 and coeffient of kinetic friction is 0.4. theta is measured below the horizontal

physics
A block sits against a vertical wall and a 120 lb force P acts diagonally to the left on the block at an angle below the horizontal. Determine the magnitude and direction of the friction force which the vertical wall exerts on the 100 lb block if theta is (a)15 degrees (b)30 d...

I need help asap please Which figure above, if any, is topologically equivalent to the given figure? Identify the topologically equivalent figure by letter. A pretzel a.pencil b.pipe, c.trophy

physics
this still isn't the correct answer though. my book says that it's 0.204

physics
Each of the four wheels of the vehicle weighs 40 lb and is mounted on a 4in diameter journal. The total weight of the vehicle is 960 lb, including wheels, and is distributed equally on all four wheels. If a force P = 16 lb is required to keep the vehicle rolling at a constant ...

So the answer for #1 is 1/35 is that I have to do for that problem though?
