Part A A spring of force constant 240.0 N/m and unstretched length 0.220 m is stretched by two forces, pulling in opposite directions at opposite ends of the spring, that increase to 15.0 N. How long will the spring now be? Express your answer in meters. V ΑΣφ m = 1 Submit Request Answer Part B How much work was required to stretch it that distance? Express your answer in joules.
Problem 1 A 1-kg block is 3 meters from a light spring. The coefficient of kinetic friction between the floor and the block is 0.25 (the coefficient of friction is the same on the entire surface). The block has a speed of 3 m/s when it hits the spring that has a force constant of 50 N/m. The block comes to rest when it has compressed the spring a maximum distance d. Find: 1. The speed of the object at the beginning of the 3 meters. 2. The value of the maximum compression d. k m
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).
