A 5 kg wooden block sitson a flat straight-away12 meters fromthe bottom of an infinitely long ramp, which has an angle of 20 degrees. The straightaway has a coefficient of kinetic friction of 0.4and the ramp of 0.25. While the block is on the flat section, youexerta 100 N forceat an angle of 45 degrees above thehorizontal, propelling the block towards the ramp.a.What is the velocity of the block right before it begins going up the ramp?b.How far up the ramp(the distance along the hypotenuse)does the block travel before stopping?

A 0.0147-kg bullet is fired straight up at a falling wooden block that has a mass of 2.94 kg. The bullet has a speed of 760 m/s when it strikes the block. The block originally was dropped from rest from the top of a building and had been falling for a time t when the collision with the bullet occurs. As a result of the collision, the block (with the bullet in it) reverses direction, rises, and comes to a...

A 2.4 kg block hangs from the bottom of a 2.0 kg, 1.6 m long rod. The block and the rod form a pendulum that swings out on a frictionless pivot at the top end of the rod. A 10 g bullet is fired horizontally into the block, where it sticks, causing the pendulum to swing out to an angle of 45 degrees. You can treat the wood black as a point mass. What is the moment of inertia of...

A 0.004 kg bullet is fired into a 0.200 kg wooden block at rest on a horizontal surface. After impact, the embedded bullet block slides 8.00 m before coming to rest. If the coefficient of friction is 0.400, what is the speed of the bullet before impact? a) 96 m /s b) 112 m/s c) 286 m/s d) 404 m/s e) 812 m/s

A 4.0- kg wooden block rests on a level table. The coefficient of friction between the block and the table is 0.23. A 5.0- kg mass is attached to the block

A 4.0- kg wooden block rests on a level table. The coefficient of friction between the block and the table is 0.23. A 5.0- kg mass is attached to the block by a horizontal string passed over a frictionless pulley of negligible mass. Now, the 5.0- kg mass is released and the whole system accelerates. What is the acceleration of the wooden block? What is the tension in the string during the acceleration? Determine the acceleration for the above situation when the coefficient...

A 0.17- kg block on a wooden table is given a sharp blow with a hammer. The block then slides across the table to a stop. The coefficient of friction between the block and table is 0.38. The hammer's force on the block as a function of time is well approximated by an isosceles triangle with it's base on the horizontal time axis. The length of the base is 0.0074 s and the maximum force is 48.5 N. How far...

(a) A 60 kg person, is in a room that is 6 meters long. Can this person be certain that they is not moving, even if to all appearances they are sitting perfectly still? If not, then estimate within what range their velocity is likely to be (you may assume that their average speed is zero). (b) Find the size of the smallest one-dimensional box in which you can confine an electron, in order to be sure that the speed...
