the friction force and applied force?

to find the horizontal force would you have to multiply the mass by the coefficient of friction?

Homework Statement [/B]A 5228 kg flatbed truck has a 226 kg crate resting on the level bed. If the static coefficient of friction is 0.27, what is the maximum acceleration the truck can achieve without the crate slipping off?Homework Equations [/B]f=maThe Attempt at a Solution i believe i need...

i have drawn a bunch of different ways, and it still makes no sense because none of the lines were parallel. i am completely stuck right now on this question

it does not say what the angle measurements are though

yeah i drew a picture but it ended up looking like a rectangle. and my work is posted in the post right above yours

Homework Statement [/B] A plane flies the following paths: 168 km to the Northeast, 144 km to the Southeast, 246 km to the Southwest, and then 127 km to the Northwest. At the end of the trip, how far was the plane from the original airport? Homework Equations [/B]Pythagorean theorem...

Homework Statement [/B]Find the normal force exerted on a 68.2 kg blacksmith's anvil by the level block of wood that is supporting it.Homework Equations [/B]f=ma Ff=uFnThe Attempt at a Solution [/B]I have tried to find all the forces acting on the anvil while using its mass but I am not...

ok i found it thank you

ok that's where i messed up, so the acceleration is 288/1490 which is .193m/s^2?

well first i found the force by multiplying m and a, then i subtracted the friction force which is 288n. i got the force as 32790 and this is where i got stuck. i thought the acceleration is 22.2m/s^2?

Homework Statement A 1490 kg car is is traveling at a speed of 22.2 m/s when the driver let's the car coast on a level road. The friction on the car slowing it down is 288 N. How far will the car coast? Homework Equations f=maThe Attempt at a Solution i can find the force but i cannot find...
