A mass is leaning against a spring, compressed of a distance d = 50 cm. Compute the speed of the mass when it reaches the equilibrium point of the spring. The mass is detaches from the spring and moves on a rough surface. Compute the distance crossed by the mass. If also the first distance d = 50 cm is a rough surface, compute the final distance crossed by the mass.(NB: mass = p kg, coefficient of friction = q spring constant = k N/m where p, q and k are dimensionless constants) Compute the speed of a mass starting with zero speed, moving on a rough, inclined plane of length 1 = 20 m, inclination 0 = 30°, subject to a dynamic friction of coefficient ud = 0.3.

- H1. A wooden block of mass m is pushed over a floor in a straight line in the x direction with a constant velocity vo > 0. At time t = 0, when the block is at position x = 0, it is no longer pushed and the block experiences only a constant sliding friction force F in the negative x-direction until it comes to rest. (i) Write down the equation of motion of the block for t > 0. Calculate the time, t, at which the block comes to a stop and also find the distance, d, travelled by the block from the time when the pushing is stopped to the time when it comes to rest. (ii) Calculate the work done by the friction force from x = 0 to x = d, and then show that it is equal to the change in the kinetic energy of the block.
