A block of mass m is held against a spring of spring constant k which is compressed a distance Ax.
On the shaded region (d = 2 m), there is a coefficient of kinetic friction = 0.3 microcontroller, which then applies the
rest of the course takes place without friction. The loop has a radius r. If m = 0.4 kg, k = 175 N / m, Dx = 0.28 m and
r = 0.7 m:
a) Calculate the standard applied by the loop on the block when it is at the top of the loop.
b) Calculate the modulus of the speed of the block at point P, that is to say, just before leaving the track.
c) Calculate the horizontal distance R that will cross the block.
d) What is the kinetic energy of the block when it reaches its maximum height?
