- A spring is oriented vertically and compressed by a distance of 0.098. It has a spring constant of 5 100 N/m. A block with a mass 0.255 kg is placed at rest on the upper end of the sprng. When the block is released, it moves upward and leaves the spring. To what maximum height above the point of release does it rise? (Round to the nearest 2 decimals)The problem uses the ideal spring force, in one dimension. F = -kx, where x is the deviation from equilibrium, and k is the spring constant. Calculate the particle's maximum speed (vmax), with these numbers: k = 2000 N/m = 2000 kg/s2 m = 5 kg (the mass of the particle) x0 = 0.2 m (the initial position) v0 = 5 m/s (the initial velocity) The all-too-common erroneous solution: v max = A ω = x 0 k / m = 0.2 m ⋅ 20 / s = 4 m/s . Your problem: You may not understand this problem fully, and may not be able to solve it. Nevertheless, spot the egregious wrongness of the answer.A spring has a force constant of 18.9 N/m and a rest length of 0.35 m.The spring is stretched to a length of 1.2 m and attached to a mass of 0.45 kg. When the spring is released, what is the speed of the mass when the spring has contracted to 0.70 m long?

If the spring constant is 105 N/m, how fast will the mass be moving when it reaches the equilibrium position? Hint: You cannot ignore the change in gravitational potential energy in this problem. Please give you’re answer in m/s.A large toy car is pushed horizontally by a spring, and the spring has a spring constant of 135 N/m. What is the mass of the toy car if compressing the spring 0.055 m (before the toy starts moving) causes it to reach a speed of 0.75 m/s? (Note - the height of the toy does not change.)
