Part A A block with mass 0.50 kg is forced against a horizontal spring of negligible mass, compressing the spring a distance of 0.20 m (Figure 1). When released, the block moves on a horizontal tabletop for 1.00 m before coming to rest. The spring constant k is 100 N/m. What is the coefficient of kinetic friction uy between the block and the tabletop? ΑΣφ Hk = Submit Request Answer Provide Feedback Figure < 1 of 1 k - 100 N/m m = 0.50 kg H0.20 m 1.00 m
K L water M A 5.10 kg mass attached to a spring is travelling at a speed v; at point K, as shown above. While it is falling it is also being pushed by a spring (k = 475.00 N/m) compressed by 1.60 m (at point K). The mass travels 1.60 m (between K and L) then hits a pool of water at point L where the water exerts an average force of 54.80 N [upwards]. At point L the spring is no longer pushing and begins to stretch (in other words, at point L, x=0). The mass eventually stops at point M. If the distance between L and M is 7.45 m, determine the initial velocity of the mass (v;). Enter an answer with three digits and in S.I. units.
