N m' (i) For the purpose of an experiment, a 2.6 kg block is placed on a frictionless plane inclined at 45 with the horizontal. The block is pushed against a massless spring with a spring constant of k= 3520 compressing it by 20 cm. (a) Find the elastic potential energy of the spring, while is compressed by 20 cm. (7p) (b) If the box is suddenly released, how far along the incline will it slide until it stops for a moment? (4p) ww (ii) Assuming that there is now friction (coefficient of kinetic friction is = 0.24) between the block and the inclined surface, repeat the calculation for the maximum distance travelled along the inclined plane.
