A 8 kg block sits on a ramp inclined at 12 degrees that has a coefficient of friction of 0.5. A string runs from the block over a pulley at the top of the ramp and then hangs straight down to a suspended weight. If the block slides up the ramp at constant velocity, find the mass of the suspended weight.
A block (425‐kg) is sitting on a ramp, which is angled 25.0‐degrees above the horizontal. A rope pulls up the ramp with 275N and another rope pulls horizontally at 175N. The coefficient of static friction is 0.855. The coefficient of kinetic friction is 0.655. a. Draw a free‐body diagram for this case. Make sure to indicate a coordinate system. b. Write out Newton’s 2nd Laws, once for each dimension. c .Determine the acceleration of the block. d. Pick one force from your free‐body...
A 9.00 meter long ramp is inclined at an angle of 6.00 above horizontal. A 7 kg box is given an intial push at the bottom of the ramp so that when it gets to the top it stops. The coefficient of kinetic friction between the box and the ramp is .230 a) what is the initial speed of the box just as it is pushed. (The answer is 7.68 m/s, but I can't seem to set it up properly...
a) what was the acceleration of the block down the ramp before
the rope is pulled?
b) what was the acceleration of the block down the ramp after
the rope is pulled?
A4 kg block is released from rest at the top of a frictionless plane of length 9m that is inclined at an angle of 21 degrees to the horizontal Acord is attached to the block and trails along behind it. When the block reaches a point 3 m...
A large rough ramp is inclined φ=35 degrees above the horizontal. A block of mass m = 5 kg is sliding on the board and the coefficient of kinetic friction between the block and the ramp is μk=0.3 . The block is tied to a string of length L = 0.25 meters so that the block moves about a circular trajectory. HINT: I'd recommend drawing the FBDs from a side-view. a) Draw a complete FBD of the block at the...
2. a- A 1.5 kg block slides down an inclined ramp with u 0.4. If the ramp angle is 17.0° and the length of it is 30.0 m, assuming it started sliding at 5 m/s. Find the speed of the block as it reaches the end of the ramp b- a- A 3 kg block is pushed against a spring with negligible mass and force constant k 4500 N/m, compressing it 0.220 m. When the block is released, it moves...
A block slides down a frictionless ramp, which makes a 30 degree angle to the horizontal floor. The block slides the full 180m all the way down the ramp, where it encounters a flat surface with friction. It slides for 250m before it finally comes to rest. a.) what is the speed at the bottom of the ramp? b.) What is the coefficient of friction on the flat surface? c.) What is the total time the block was in in...
Our favorite crate full of
armored armadillos is sitting at the bottom of a hill that is
inclined 41° above the horizontal. The crate is 75 kg and the
coefficient of kinetic friction between the crate and the ground is
0.31. Samer decides to drag the crate to the top of the hill, which
is 20 m above the base of the hill. Samer attaches a thin rope to
the crate so that when he pulls, the rope will be...
A skateboarder with mass m_ s = 52 kg is standing at the top of a ramp which is h_ y = 3.6 m above the ground. The skateboarder then jumps on his skateboard and descends down the ramp. His speed at the bottom of the ramp is v_ f= 6.8 m/s. Randomized Variables m_ s= 52 kg h_ y = 3.6 m V_ y= 6.8 m/s Write an expression for the work, w_ f, done by the friction force...
2. A 5 kg block sits at rest on an inclined ramp which makes an angle of 24 degrees with respect to the horizontal. It is noted that even if the angle 0 is increased the block still does not slip. The coefficient of static friction for the bottom surface of the block and the surface of the ramp is us= 0.56. The magnitude of the frictional force acting on the block must be O 1 O O A. 50...
