A block slides from rest, along a track with an elevated left
end, a flat central part, into a relaxed spring, as shown in the
figure. The curved portion of the track is frictionless, as well as
the first portion of the flat part of L = 10 cm. The coefficient of
kinetic friction between the block and the only rough part, D = 10
cm, is given by k = 0.20. Let the initial height of the block be...

Need help solving for d) and e)
26. Protons are projected with an initial speed v GP 9.55 km/s from a field-free region through a plane and into a region where a uniform electric field E 720j N/C is present above the plane as shown in Figure P22.26. The initial velocity vector of the protons makes an angle θ with the plane. The protons are to hit a target that lies at a horizontal distance of R 1.27 mm from...

We usually ignore the kinetic energy of the moving coils of a spring, but let's try to get a reasonable approximation to this. Consider a spring of mass M, equilibrium length L0, and spring constant k. The work done to stretch or compress the spring by a distance L is , where X = L - L0.Part AConsider a spring, as described above, that has one end fixed and the other end moving with speed v. Assume that the speed of points along...

A bullet (0.1 kg) initially moving at speed u is embedded inside block 1 (4 kg) initially at rest at A which travels 8 m in a rough region (uk = 0.2) to B at speed of 12 m/s, then travels to a frictionless region from B to C, then to a rough region (Uk = 0.2) after point C. Then bulletblock 1 collides with block 2 (15 kg) which is initially at rest and connected with a spring of...

Practice Problem 18.3 Constants Now let's look at the potential energy of a charge that is in the vicinity of two other charges. Suppose two electrons are held in place 10.0 cm apart. Point a is midway between the two electrons, and point b is 12.0 cm directly above point a. (a) Calculate the electric potential at point a and at...
